Thanks for writing in! You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
No. Deactivating any plugins will not remove any settings or information. If the plugin displays the information, it will be temporarily will not be displayed once the plugin is inactive.
