Have you ever had a problem where one is the problem? But which one? This plugin shuts off all your active plugins one at a time to see if one of them affects the final look. It also lets you test one page to see what it looks like.
Do you want to try it out and see if this helps?
After installation and activation, the “Plugin Checker” element is available under the plugins to let you check your plugins one by one, but automatically.
