In my case the culprit was a lightbox implementation of the JotForm feedback. It loads some kind of external javascript which in this case disabled functionality of the tabs and spoilers (I don’t know why it did this). I changed this function to a popup to disable the externally loaded javascript.

The Jotform feedback was something which I added manually into the theme files, so a simple check to see if it is your theme files that are problematic is to just put a random tab or spoiler function on your start page and live preview another theme. If the tabs work, then something in the theme you are using is causing the problem.

The new version solved the issue. Thank you very much for your help.

We recently found that it did not have anything to do with the WordPress update, but it was an externally loaded javascript that interfered with the tabs function.

With the latest update the error messages are gone. Thank you ??

Same problem here. Plugin is unusable if I can’t add things from the visual editor.

Wow, that was a quick update to fix the problem. Thank you, it works like a charm now ??
