Hey @RPronk,
I checked your site and the footer is being displayed.
I then checked if there’s an issue with the builder so I’ve added an element and still it saved successfully and the updated footer is being displayed.
Since you have not updated, I then tested adding a link with target blank and that’s when your footer disappeared. With that said, you should update to the latest version of Pro. For more details about the issue and the fix, please see the specific update in our Changelog: https://theme.co/changelog/#theme-pro-2-4-7
Please always check our Changelog to see what has been fixed and test the latest update in a staging site.
Hope that helps.
