- Disable All Plugins.
A good first step is to disable all of the plugins on the site.
If the problem is gone, you may re-enable the plugins one by one until the problem is back. When the problem resumes, you can be fairly certain that the plugin that was just enabled is causing or is related to the problem.

Changing the theme of the site to one of the default WordPress themes is a great way to determine if your theme is the source of the problem
