@Loren The issue was advanced footer not parsing settings in my pluign theme hook for some reason, this is a bug in IPS plugins as it happened to me once, and it only happens when you update plugins, Im not sure how to reproduce to report as it happened to me only once
due to this issue, twitter javascript callback in my plugin were always added without the need of enabling its setting in the pluign, and this could cause issues
Anyways, I just deleted the advanced footer and reinstalled it again in your website, the error was showing in console has gone now and everything seems to work fine, i also checked the re-ordering of tabs in Clubs Enhancements, no issues anymore.
Don't worry, your footer blocks and customizations are not deleted, everything is same
Have a good day.
