Hi Sandra,
Thank you for writing, what content do you place on your Main Footer, is there a script on it? Please provide a walk-through on how we can replicate the issue.
In the meantime, I see a couple of errors on your site that causes by a plugin, please do 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.
Another thing, I see you have an updated version of Wordpress (5.2.4) but an old version of PRO (2.4.6), please update PRO to the latest version (3.0.4) to make sure that this is not an incompatibility issue.
Updating Your Themes and Plugins
Remember to clear all your caching features (plugin, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Let us know how it goes,
Cheers!
