After 5 hours of debugging, I think I found the !@#!$ plugin that was doing this…..
Simple Links
That was the last plugin I have added in my installation. After deactivating this, everything was smooth again!!!
Same problem here! I haven’t update or add anything!
I get this error
TypeError: element.visible is not a function
