PrestaShop back office error 500 or blank page - Fix it Now ?


This article covers methods to resolve PrestaShop back office error 500.

The error happens when the Back-office is accessed only from Debug mode activated or in production mode activated. The characteristic of this error is that it only occurs in one of the modes and not in both.

Also, this is an error that is occurring ONLY IN PRESTASHOP STORES VERSION 1.7, and that makes it impossible for us to enter the Back-office, showing an error 500 or the page goes blank. 

That's why we call it a critical mistake, for leaving the store inoperative.


To fix a HTTP 500 error on PrestaShop online store website:

You can activate your web host's FTP or CPanel error reports in your PrestaShop shop.

1.  From PrestaShop v1.4 to v1.5.2

i. Open config/config.inc.php

ii. On line 29, you will find this line: @ini_set('display_errors','off');

iii. Replace it with: @ini_set('display_errors','on');


2. PrestaShop v1.5.3 and later versions (including 1.6 and 1.7)

i. Open config/defines.inc.php

ii. On line 28, you will find this line: define('_PS_MODE_DEV_', false);

iii. Replace it with: define('_PS_MODE_DEV_', true);

Once error reports from the FTP or CPanel are activated, you can browse your store's front or back office to find out what the problem is.


More about Server error 500:

Error 500 means Internal server Error. Whenever a 500 error occurs, the task to return information by the server to the web browser will stop. 

Therefore, as we mentioned above, this is a critical error that would leave the website inoperative.

The 500 errors, as we noted above, are internal server errors and their origin may be in a programming code error on any item that is included and related to the request for information returned by the server to the web browser. 

Therefore, not all 500 errors come from the same source.

WordPress error "Could Not Save Password Reset Key To Database" - Fix it Now ?


This article covers methods to resolve WordPress error "Could Not Save Password Reset Key To Database" which usually occurs when we try to login into our WordPress site.

As the database is part of the hosting space, you'll get that database error when you fill-up the entire available disk space of your account.
That can happen if you created several staging sites or uploaded too many large files like big images on your website.

A more common reason for this WordPress issue can be substantial backup files created by your backup plugin.

Backup files need a lot of space on your system, which can quickly fill up the entire available webspace.
1. So to fix this WordPress error, immediately log in to your website using an FTP client like the Filezilla program or the File Manager in your cPanel hosting dashboard.
2. Then go to the media folder wp-content/uploads and check there for large files which you can delete, for instance, backup files with the ending .*zip or large media files with the file extension *.tiff, *.png, or *.png.
3. You should never use the *.tiff format, though. This one uses a lot of disk space, so it's better to use *.jpg instead of that.
4. After, open your WordPress website, log in, or use the password reset function again.

To fix this WordPress error in cPanel:

1. You'll need to free up space on your server.
2. Log into the HostPapa Dashboard and click My cPanel.
3. Then select Files > cPanel File Manager.
4. Navigate to your WordPress root folder and select wp-content/uploads.
5. Search through your upload files to locate and delete large files that you may no longer need.
6. Click the Size link to sort the list by file size.
7. Take a look elsewhere on the server for files and folders you are happy to delete.
8. Once you've created some space on your server, you can attempt to log into WordPress once again.

Undefined index notice in Joomla - Fix it now ?


This article covers how to resolve Undefined index notice in Joomla. A notice, in PHP terms (PHP is the scripting language that powers Joomla), is more or less a complaint. For example, if you're using a deprecated function such as ereg_replace (by the way, we have had quite a few sites with the ereg_replace() is deprecated notice that we needed to fix) then PHP will complain with a notice.
A notice may also be displayed if you're trying to use questionable casting that PHP thinks will not return the result that you want (for example, if you try to forcefully cast an array into a string).

To fix this Joomla warning:

Change PHP's error reporting in the .htaccess file to hide all errors.
You can do that by adding the following code to your .htaccess file:

php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on

The above code will ensure that no error whatsoever will be displayed on your website.

Note that if you have an Error Reporting setting in your configuration settings other than "Default", then this setting will override the error reporting defined in your .htaccess.
For example, if your Error Reporting is set to "Maximum", then the above code in your .htaccess file has no effect.

Shopify error 429 too many requests - Fix it Now ?


This article covers Shopify error 429 too many requests. Basically, 429 too many requests can trigger due to increased number of API requests.
Calls to the REST Admin API are governed by request-based limits, which means you should consider the total number of API calls your app makes.

In addition, there are resource-based rate limits and throttles.

To avoid rate limit errors in Shopify:

Designing your app with best practices in mind is the best way to avoid throttling errors.
1. Optimize your code to only get the data that your app requires.
2. Use caching for data that your app uses often.
3. Regulate the rate of your requests for smoother distribution.
4. Include code that catches errors. If you ignore these errors and keep trying to make requests, then your app won’t be able to gracefully recover.
5. Use metadata about your app's API usage, included with all API responses, to manage your app’s behavior dynamically.
6. Your code should stop making additional API requests until enough time has passed to retry.

The recommended backoff time is 1 second.

"Are you sure you want to do this" error in WordPress - Fix it Now ?


This article covers methods to fix 'Are you sure you want to do this' error in WordPress for our customers.

One of the most common solutions is to revert your website to an older backup before the error occurred. If you update your backup regularly, it is one of the most powerful tools to use against errors.
If you do not update regularly, the backup is close to worthless because it is missing your regular content updates and website changes.

To fix "Are You Sure You Want to Do This" Error in WordPress:

1. You will not need any additional plugins to solve this issue and in fact, a plugin is likely causing the issue. The error is very simple to track but can become quite tedious if you have a lot of plugins and themes installed. The process includes disabling your themes and plugins while checking to see if the error is fixed. If you have a lot of plugins, this process may take a while. Deactivating the plugins will not be enough because they can still cause a problem. This is why it is recommended to uninstall a plugin if you are not using it.
2. Log into the cPanel and click on the File Manager. Click on the public-html directory and locate the wp-content folder. This folder contains all of the content on your website. Locate the plugins folder and right-click it.
Select the Rename option and rename it to "plugins off" or something similar.

Googlebot cannot access CSS and JS files – Resolve crawl errors ?


This guide covers website crawl errors, Googlebot cannot access CSS and JS files. Google bot and other search spiders will visit the robots.txt file of your website immediately after they hit the htaccess file.

Htaccess has rules to block ip addresses, redirect URLs, enable gzip compression, etc. The robots.txt will have a set of rules for the search engines too. 

They are the reason you received "Googlebot Cannot Access CSS and JS files". 

Robots.txt has few lines that will either block or allow crawling of files and directories. Google has started penalizing websites that block the crawling of js and css files.

The JavaScript and cascading style sheets are responsible for rendering your website and they handle forms, fire events, and so on.

If the JS is blocked, Google bot will not be able to crawl the code and it will consider the code as a spam or violation of link schemes. 

The same logic applies for the CSS files.


To resolve "Googlebot Cannot Access CSS And JS Files" Warning:

1. You need to remove following line: Disallow: /wp-includes/

Depending upon how you have configured your robots.txt file, it will fix most of the warnings. 

You will most likely see that your site has disallowed access to some WordPress directories like this:

User-agent: *

Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/themes/

2. You can override this in robots.txt by allowing access to blocked folders:

User-agent: *
Allow: /wp-includes/js/

To Fix SQL Server Error 9002:


1. Backup Transaction Log File

Incase, SQL database that you are using is full or out of space, you should free the space. For this purpose, it is needed to create a backup of transaction log file immediately.

The free space on disk will allow users to perform other task and resolve SQL Error Log 9002 The Transaction Log for Database is Full.


3. Move Log File to a Different Disk

If you are not able to free the space on a disk drive, then another option is to transfer the log file into a different disk. Make sure another disk in which you are going to transfer your log file, has enough space.

i. Execute sp_detach_db command to detach the database.

ii. Transfer the transaction log files to another disk.

iii. Now, attach the SQL database by running sp_attach_db command.


4. Enlarge Log File

If the sufficient space is available on the disk then you should increase the size of your log file. Because, the maximum size for a log file is considered as 2 TB per .ldf file.


To enlarge log file, there is an Autogrow option but if it is disabled, then you need to manually increase the log file size.

Microsoft SQL Server Error 916 - Fix it now


This article covers method to resolve Microsoft SQL Server Error 916 for our customers.

The main problem is due to bugs present in SQL Server Management Studio that prevents the user to connect to the database and refuses to display the database list.

How to solve Microsoft SQL server error 916:
If you receive the following error while using Microsoft SQL Server Management Studio 2008:
The server principal "username" is not able to access the database "dbname" under the current security context. (Microsoft SQL Server, Error: 916).

Causes of SQL Server Error 916:
1. The user is not permitted to view the data of selected column within the database.
2. The database is currently not available.
3. There are multiple columns such as Size, Space available, Data Space Used, Default file group, Index Space Used, Mail host, Primary file path and user has added at least one of them to the list of Object Explorer Details.
4. If the Auto Close option for the database is enabled, then Collation column cannot be retrieved by SQL Server Management Studio (SSMS).
5. For a database, Collation column contains NULL.

In order to view the granted permissions for the guest-user, the following command is helpful if run by a member of a Sysadmin fixed server.
The query is as follows:

USE msdb;
 SELECT prins.name AS grantee_name, perms.*
 FROM sys.database_permissions AS perms
 JOIN sys.database_principals AS prins
 ON perms.grantee_principal_id = prins.principal_id
 WHERE prins.name = ‘guest’ AND perms.permission_name = ‘CONNECT’;
 GO

On running the above command, a table is presented to the user containing all the attributes of guest user.
However, an empty result shows that guest user is disabled in the database and again the SQL Server error 916 will be displayed.
To overcome the error you may perform the following available solutions.

To fix this SQL server error 916:
1. In Object Explorer, click databases.
2. Display "Object Explorer Details" (F7) or "View –> Object Explorer Details".
3. Right-click the column headers and deselect "collation".
4. Refresh the databases.

Attributes do not match - Fix this SQL Server Installation Error


This article covers how to resolve the error, SQL Attributes do not match. Basically, the error, Attributes do not match occurs during SQL Server installation or during SQL Server patching activity.
Once you get this issue, you can check all drives available on your database server whether they are compressed or not. If any drive is compressed and SQL Server is using that drive during installation then that might be the reason for getting issue Attributes do not match.
You need to uncompress all such drives and then start the installation.

To uncompress the drive we need to launch property window of that drive:
1. We just need to right click on the identified drive and choose Properties to see the status of compression.
2. You can see compress this drive to save disk space option is ticked.
3. Uncheck this option and click on OK button to apply the change.

When installing SQL server and running into an error "Attributes do not match.
Present attributes (Directory, Compressed) , included attributes (0), excluded attributes (Compressed, Encrypted)".
This is because you are trying to install SQL into a folder that is compressed which is not supported.
To fix this;
1. Navigate to C:\Program Files\Microsoft SQL server folder
2. Right click on properties on SQL Server folder.  
3. Under advanced option in general tab, look for compress contents to save disk space, uncheck it.
4. Also, uncheck "encrypt contents to secure data"
5. Re-run the SQL install

Nagios No lock file found - Fix this error now


This article covers different methods to resolve the error, Nagios: No lock file found.  Basically, "No lock file found in /usr/local/nagios/var/nagios.lock" means that the service isn't running.

To fix this Nagios error:
Execute the command:

$ /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

Running the command above simply starts the nagios daemon and points it to a specific config file.
The advantage to running this command manually over systemd is that when you run "service nagios start" this typically calls the /etc/rc.d/init.d/nagios script which contains a line with parametrized environment variables:

$NagiosBin -d $NagiosCfgFile

Because every system is different, not specifying either the bin nor config directories could lead to nagios breaking (stopping) when it tries to start using the default installation directory paths
