How to Fix 500 Internal Server Error in WordPress.
500 Internal server error in WordPress can be caused by a variety of issues like:
issue 1. Problems with your .htaccess file
issue 2. Plugin or theme compatibility issues
issue 3. Insufficient PHP memory
issue 4. Corrupted WordPress core files
1. One common cause of the 500 Internal Server Error in wordpress is a corrupt .htaccess file. This is one of the first things to check because fixing the .htaccess file is relatively easy to do.
Your .htaccess file contains important configuration options for your server. Even a small change to your .htaccess file can cause the 500 Internal Server Error. These changes can often be applied automatically by security and cache plugins, as well as anti-spam and redirection plugins too.
To fix your .htaccess file, you need to:
Rename your existing .htaccess file via FTP
Check if your WordPress dashboard is now accessible
Generate a new .htaccess file via WordPress
2. Deactivate Your Plugins to Check for Plugin Issues.
If you’re still having issues, your next step is to deactivate all of your plugins to see if that fixes the issue.
If your site starts working after deactivating your plugins, you know there’s a plugin that’s at least indirectly causing the issue.
Reactivate your plugins one by one until you find the culprit.
3.Increase the PHP Memory Limit For Your Site/Server
Another potential cause of the error is that your site is hitting its PHP memory execution limit.
Sometimes a plugin may use a large chunk of your memory, which causes your site to hit the limit.
This is one of the reasons deactivating your plugins can often get your site working again, at least temporarily. Create a blank text file called php.in Paste this code in there:
Save the file.
4. Re-upload wp-admin and wp-includes Folders
If nothing has worked so far, a long-shot solution is to try re-uploading your wp-admin and wp-includes folders to fix any potentially corrupted files.
