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.
