When you attempt to customize your site via Appearance → Customize or your theme options or builders, you may get an Internal Server Error (HTTP 500 range).
This is usually a plugin conflict.
Can you access your WordPress admin?
if no, skip to the next section
If yes, continue:
- Go to Dashboard → Updates and ensure your theme and plugins are updated. Plugins that come bundled in your theme will notify you they need updates and direct you to a special page to update them. See How To Update Your Theme
- If you are using a child theme, go to Appearance > Themes and activate the main theme, then retest the action that produced the error. If this solves it, your child theme may be causing the problem and you will need to debug it with the child theme creator.
- If you have run a WordPress Reset on your site and are now getting HTTP500 errors, please contact us to ensure your theme is installed and registered correctly.
- Go to
→ and ensure Post Name is selected, then click Save to regenerate all links, then test again.
- If the error still occurs, go back to Settings → Permalinks and choose Default, then test again. If this works, the issue may be theme related.
- Click the Flush Object Cache button in your admin toolbar at the top of the screen.
- Check all three boxes and click flush
- Click OK
- Go to and deactivate all plugins.
- Try the action that produced the error again.
- If this works, click around your menu to visit other pages and ensure they work.
- You will need to reactivate plugins one at a time and test after each until you find the one causing the problem. Please review our disallowed plugin list to make sure you do not enable any caching or security plugins that could be causing the problem.
This error is almost always due to a plugin conflict or truncated process on the server.
To prevent this error from occurring while you're working in the admin, never update or install multiple plugins at once using the Bulk menu, for example. The following walks you through how to regain access to the admin.
If you are uncomfortable with this process, please contact us using this link
- Connect to your site via FTP
- Open the wp-content folder and rename plugins to plugins-old
- You should be able to login to the admin now - visit the Plugins page and all plugins will be force-deactivated. Continue with the steps in the first section above.
- If trenaming the plugins folder does not allow you back in, go into the themes folder and rename your theme folder. For example dt-the7 can be renamed to dt-the7-off
- Try accessing your admin now. If this works, your theme is causing a problem - please contact us to reload the theme.
- Rename the plugins-old folder back to plugins
- Delete any known-problem or disallowed plugins in this article.
- Follow the theme's recommended plugin installer to update or activate any noted plugins one at a time if you see a notice in your dashboard
- If none of the bundled plugins cause the error to reappear, continue to reactivate plugins one at a time. If any of them cause the issue again, delete the plugin and notify the customer they will need to replace it (or find a replacement for them)
Note: There may also be a theme update available - please check and perform any theme and bundled plugin updates if needed.
