The WordPress Missed Schedule post Error - Methods to fix it
This article covers how to easily fix the missed schedule post error in WordPress. WordPress scheduled posts not publishing can be resolved by using a plugin such as "WordPress cron jobs" to help trigger scheduled posts to publish your WordPress Post.
Cron is a technical term for commands that run on a scheduled time, like your scheduled posts in WordPress.
Technically, a real cron job will run at the server level. But because WordPress doesn't have access to that level, it runs a simulated cron.
These simulated cron jobs, like scheduled posts, are supposed to be triggered whenever a person or bot visits your site.
But because it's not a real cron job, sometimes it causes a missed schedule error.
TO FIX THE MISSED SCHEDULE ERROR IN WORDPRESS:
Every fifteen minutes the post scheduler plugin checks for posts that have the missed schedule error, and will automatically publish them for you.
Multiple techniques for checking your site's missed posts are used to make sure a scheduled post is not missed.
Methods to fix the WordPress missed schedule error:
1. Use the Scheduled Post Trigger plugin.
2. Manage cron jobs directly through your server.
How to setup AWS CloudFront and how it delivers content

Troubleshoot DNS issues - Step by Step tips to resolve it
This article covers how to troubleshoot DNS issues. One of the handiest tools for troubleshooting DNS failures is the NSLOOKUP command, which you can access from a Windows Command Prompt window. Simply type NSLOOKUP followed by the name of the host for which you want to test the name resolution.
Basically, DNS errors are caused by problems on the user end, whether that's with a network or internet connection, misconfigured DNS settings, or an outdated browser. They can also be attributed to a temporary server outage that renders the DNS unavailable.
DNS: online name resolution:
The domain name system (DNS) is a directory service used for transforming alphanumeric domain names into numeric IP addresses.
A decentralized process, name resolution generally takes place on DNS servers’ networks distributed throughout the world.
Every internet address you enter into your web browser’s search bar is then forwarded by your router to a DNS server. This server then dissolves the domain name into a numeric sequence and returns a corresponding IP address.
Should the DNS server fail to produce an answer, then it won’t be possible to access the desired website; the result is the error message ‘DNS server not responding’.
To clear your DNS cache:
1. On your keyboard, press Win+X to open the WinX Menu.
2. Right-click Command Prompt and select Run as Administrator.
3. Run the following command: ipconfig /flushdns.
To Troubleshoot DNS issues:
The root of such irritating messages can often be traced back to the server outage. In such cases, the DNS server is temporarily unavailable. Most of the time, these problems can be corrected by changing browsers, switching a few of your firewall settings, or restarting your router.
1. In order to rule out that the connection problem isn’t being caused by your web browser, carry out a test by attempting to logon on to the desired web page with alternative applications.
2. In case you aren’t able to achieve your desired results simply by changing browsers, then the next step is to rule out Windows Firewall as the possible culprit.
3. Connection problems can often be solved by restarting the server. Most devices include a power button specifically for this purpose. Should this fail to yield any results, then it looks like a hard reboot may be in store; this is done simply by pulling out the power plug.
4. If you have ruled out common causes of error such as the router software crashes or conflicts with Windows Firewall, then changing your DNS server could be the solution.
How to Check DNS server?
You can find out whether changing DNS server has solved the problem by carrying out a simple test.
Enter the URL of a well-known site in your browser (e.g. www.google.com).
If the site can be accessed it means the DNS server is functioning properly.
If the site can't be accessed, you can enter the following IP address into your browser: 172.217.16.195.
This is one of Google’s IP addresses. If Google doesn't appear after entering the address, it probably means there's a general internet problem rather than a problem with the DNS server.

Unable to allow access for disk path in libvirtd - Fix it Now
This article covers tips to fix the error Unable to allow access for disk path in libvirtd. By default, migration only transfers the in-memory state of a running guest (such as memory or CPU state). Although disk images are not transferred during migration, they need to remain accessible at the same path by both hosts.
To fix Unable to allow access for disk path in libvirtd error:
Set up and mount shared storage at the same location on both hosts. The simplest way to do this is to use NFS:
1. Set up an NFS server on a host serving as shared storage. The NFS server can be one of the hosts involved in the migration, as long as all hosts involved are accessing the shared storage through NFS.
# mkdir -p /exports/images
# cat >>/etc/exports <<EOF
/exports/images 192.168.122.0/24(rw,no_root_squash)
EOF2. Mount the exported directory at a common location on all hosts running libvirt. For example, if the IP address of the NFS server is 192.168.122.1, mount the directory with the following commands:
# cat >>/etc/fstab <<EOF
192.168.122.1:/exports/images /var/lib/libvirt/images nfs auto 0 0
EOF
# mount /var/lib/libvirt/images
