Most frequent WordPress errors

WordPress errors come in a variety of sizes and shapes. As an example, consider the maintenance mode problem or the connection timed out notification.

The most prevalent and readily repaired of the lot are 404 errors. They occur when a visitor searches for a URL that it cannot locate on your website.

Auto-upgrade issues frequently cause the WSoD. Errors in maintenance mode or compatibility issues with plugins and themes are two examples.

Suppose you find that all of your site’s pictures are suddenly broken. Alternatively, you may be unable to submit photos using the media uploader. That is very certainly due to improper file and directory permissions.

Log in to your site through FTP and browse to the wp-content directory to verify your file permissions. These are the Filezilla FTP client instructions. However, they should be the same for other FTP clients.

Select “file permissions” from the context menu when you right-click on the uploads folder within this directory.

The access for this folder and the files within it should be 755. Make certain that the “recurse into subdirectories” option is enabled. “Only apply to directories,” as well. So that all of the folders within the uploads folder have the appropriate permissions.

Right-click the uploads folder once more. You must now update the permissions of all the files to 644. Check the box to recurse into subdirectories once more. Choose “apply to files” this time.
