You can use the steps below to diagnose WordPress plugin issues.
Prepare your WordPress site for the troubleshooting:
- You should always make a backup of your site before performing any troubleshooting.
- Disable any caching plugins.
- Disable WP_CACHE if your site uses it.
Look for a plugin-related error:
- Enable WordPress debug mode.
- Visit your site and check to see if there is a PHP error.
- If there is a PHP error, check to see if the plugins directory is in the file path. Below is an example:
Parse error: syntax error, unexpected '}' in /home/html/wp-content/plugins/basic-plugin/basic-plugin.php on line 50
- If the file path contains plugins in it, then this suggests the issue is with the plugin referenced in the error, and you can move on to fixing the issue.
- If the error isn't visible on your website, then you'll need to expose the error:
- If the detailed errors or logs show a PHP error, then you can begin fixing it.
- If you can't locate an error, then you should disable all of your plugins, if you haven't already done so.
- Enable the plugins one at a time until the problem or error occurs.
- Once an error occurs, then you have likely identified the plugin causing the problem. You can then move on to fixing it.
