● Increase PHP Memory Limit: Begin by checking if your site is exceeding the allocated PHP memory limit. Many hosting providers have specific settings for memory limits. Increasing this limit can often resolve WSOD issues, especially on sites with heavy plugins or themes.
● Disable All Plugins: If the WSOD persists, try deactivating all your plugins. This can be done by renaming the plugins folder through FTP or your hosting control panel. Activate your plugins one by one to find the broken one if this fixes the problem.
● Switch to a Default Theme: It's possible that your theme is to blame if turning off plugins doesn't help. Rename your active theme's folder to revert to a default WordPress theme. If the site functions correctly with the default theme, consider changing themes or reaching out to the theme's developer for support.
● Enable Debugging: Turn on debugging mode in WordPress. This will allow you to see error messages that can help identify the source of the problem. By turning on troubleshooting logs, you can find out what might be causing the WSOD.

11. WordPress Permissions Error

The WordPress permissions error refers to an issue where the server's permissions settings restrict access to certain files or directories within your WordPress installation. This can lead to problems with uploading media, installing plugins, or updating themes, ultimately causing functionality issues on your site.

How It Occurs

Permissions errors can occur due to:
● Incorrect File Permissions: File permissions control who can read, write, or execute files. If these permissions are set incorrectly (e.g., files set to 600 instead of 644), it can prevent WordPress from accessing essential files.
● Improper Ownership Settings: If files are owned by the wrong user (not the one running the web server), WordPress may not have permission to modify them.
● Server Configuration Changes: Changes in the server environment or hosting settings can inadvertently affect file permissions, leading to access issues.

How to Solve It

Here are some solutions to address WordPress permissions errors:

● Check File Permissions: Use an FTP client or your hosting control panel to verify that file permissions are correctly set. Directories should generally be set to 755, while files should be set to 644.
● Adjust Ownership Settings: Ensure that the correct user owns the WordPress files. This often involves contacting your hosting provider for assistance.
● Disable Security Plugins: Temporarily disable any security plugins that may alter permissions settings to see if that resolves the issue.

● Corrupted .htaccess File: A damaged or misconfigured .htaccess file can prevent WordPress from correctly rewriting URLs.
● Plugin Conflicts: Certain plugins, particularly those that modify URL structures, can conflict with the permalink settings.
● Incorrect Server Configuration: Server settings that don't support URL rewriting can also cause permalink issues.

How to Solve Permalink Issues

Here are some solutions to resolve permalink issues in WordPress:

● Check .htaccess File: Ensure your .htaccess file is configured correctly. You may need to reset or regenerate it by following the WordPress documentation.
● Disable Plugins: Turn off all plugins temporarily to see if one is causing the problem. Then, reactivate them one by one to identify the source.
● Contact Hosting Provider: If you're still experiencing problems, your web host may need to adjust server settings to enable URL rewriting.

13. WordPress Image Upload Error

The WordPress image upload error is a common issue that prevents users from uploading images or media files to their WordPress site. Instead of successfully uploading an image, users may encounter error messages like "HTTP error," "file type not permitted," or "uploads folder is not writable." Here are the reasons and solutions to resolve these common WordPress errors.

How It Occurs

Image upload errors can occur due to various reasons:

● Increase File Size Limit: Adjust the maximum upload file size in your php.ini file or contact your hosting provider to increase the limit.
● Set Correct Permissions: Ensure that your wp-content/uploads directory has appropriate permissions, typically set to 755 for directories.
● Disable Plugins: Temporarily disable any plugins to rule out conflicts that may be causing upload issues.
● Check .htaccess File: Look for any directives in the .htaccess file that might be restricting uploads and adjust accordingly.

14. WordPress PHP Error

A WordPress PHP error occurs when there is a problem with the PHP code on your website, preventing it from executing properly.
