Troubleshooting WordPress

1 min read Updated

These guides help you find the cause when something on a WordPress site stops working, whatever theme or plugins you use. Common causes are a conflict between plugins or with the theme, an error in PHP or JavaScript, and rewrite rules that are out of date. If you aren’t sure where to begin, read Identifying Plugin Issues; its conflict test tells you whether a plugin or your theme is involved.

WordPress Troubleshooting

  • Identifying Plugin Issues: find a conflict between plugins or with your theme, test without affecting visitors in the Troubleshooting plugin’s Troubleshooting Mode, and get back into wp-admin when a plugin locks you out.
  • Debugging in WordPress: turn on debug logging in wp-config.php, read wp-content/debug.log, find JavaScript errors in the browser console and check Site Health.
  • Fixing Page Not Found Errors: refresh permalinks, check .htaccess, and fix changed slugs, trashed pages and old addresses.

Each guide also has an Ask an AI Assistant section with ready-to-copy prompts.
