How can I fix common WordPress errors?

I'm getting a '500 Internal Server Error' on my WordPress site. What should I do?

A '500 Internal Server Error' can be caused by various issues. First, try deactivating your plugins to see if one of them is causing the problem.

How do I deactivate my plugins if I can't access the admin dashboard?

You can deactivate plugins via FTP. Connect to your site using an FTP client, navigate to the 'wp-content' folder, and rename the 'plugins' folder to something like 'plugins_old'.

What if that doesn't work? Any other solutions?

If renaming the plugins folder doesn't resolve the issue, check your .htaccess file for any misconfigurations or try increasing your PHP memory limit.

Thanks! How can I increase the PHP memory limit?

You can increase the PHP memory limit by editing the wp-config.php file. Add this line: define('WP_MEMORY_LIMIT', '256M');
