Thank you for contacting us Jim! I am sorry to hear that there are some problems hiding the Special Thanks link in your footer and our team will do everything we can to help!
The first thing that I would check is to run any available updates to the theme installed on your website. The option to hide the Special Thanks link is tied directly to the theme and if you are running an out of date version then there could be some kind of conflict that is preventing that feature from working as expected.
Another possible explanation could be the status of the Connect key configured on your website. Hiding the Special Thanks link is only enabled for websites that use a Premium Connect key, and if you have a free key set up then that might be why there are issues hiding the link in your footer.
Hopefully running the theme updates fixes this bug on your website and please let us know if there is anything else that we can do to help!
