I have the same issue with the latest version. I’m using tab groups and a bunch of wysiwygs. The first one in the first tab i shown. The rest of them are not. Same error message as above. Happens for Chrome Mac/Win.
Edit: Well, it actually works on 2 out of 7. Seems random.
Edit 2: Turns out you cannot use certain characters in the name. Since it evaluates to an expression. The guys who originally wrote the used “:” in the name, which of course can’t be used as an selector.
Edit 3: Other weird errors has emerged. load-scripts.php?c=0&load=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,jquery…:570 Uncaught Error: Syntax error, unrecognized expression: a[href*=#], a[name*=#]
input.min.js?ver=4.4.7:formatted:1323 Uncaught TypeError: Cannot set property 'toolbar1' of undefined
Edit 4: Found the issue the child theme’s main js.
