Plugin Conflict Troubleshoot
If it’s not the theme, it might be a plugin issue. In a way, troubleshooting is similar. However, it’s much easier to rename the plugin folder to ‘pluginsOFF’. Visit the site, and log-in. This will turn off all of the plugins. Please note that it won’t remove the original settings of those plugins, as they will be there when you reactivate them later on.
Once the plugins are off, go back and rename the folder back to ‘plugins’. Go to your WordPress admin area and reactivate each, one-by-one, until you get the screen that says “There has been a critical error on your website”. The plugin that you just reactivated, is the problem.
(Change plugins folder name via cPanel)
(Change plugins folder name using FTP – Filezilla)

When you’ve discovered the issue, you probably need to rollback the subject or module that caused it. You can do this several different ways.
- Download the original plugin files directly from the WordPress plugin directory, and replace the plugin via Filemanager with your web host (or cPanel), or through FTP or sFTP.
- Use WP Rollback plugin https://wordpress.org/plugins/wp-rollback/ to roll the plugin back to the previous version.
If you use WP Rollback, it will give you several versions to choose from. It will tell you what version you have. Below, you can follow the images to get an idea of how to use WP Rollback.
Choose the plugin to rollback. Click ‘Rollback’ if it is available in the plugins listed in your WordPress admin.
Choose the version you want to rollback to.
Read the warnings. It might be better to test, before rollback. Only rollback if you’re sure.
You will want to hold off to update when the developer does another release of the plugin or theme.
