Plugins are part of what makes WordPress awesome. They allow you the ability to change themes without losing functionality. It’s for this reason we encourage the use of plugins in places where other themes might decide to include the same functionality internally. Plugins have great power over your WordPress installation, this power does, however, mean they can cause problems or conflict with one another, your theme or the version of WordPress you’re running. If you’ve encountered an unexpected problem, plugins are a great place to start.
Here are a few steps you can run through to resolve a plugin conflict or issue.
1. Head to DashboardUpdates and run any pending updates. It’s possible the problem you’re facing has already resolved. Updating all your plugins and the theme you’re running is worth a try.
2. Re-test the problem.
3. Deactivate all of your plugins at once.
4. Re-test the problem. If it’s resolved, re-activate your plugins one by one. After each activation, check the problem. When the problem re-occurs, you’ll know which plugin needs attention.
5. If you still haven’t found the cause of the problem, try switching over to a default theme like Twenty Sixteen and re-test. This should let you know if something in your theme is causing the problem.
