The hard refresh fixed it for me. Your original patch worked. I should have thought to try the refresh first. Thanks for your prompt attention and resolution.
I’ve submitted a ticket and referenced this chat (ticket # is GFS-55.). Hopefully, they will figure it out. I really like the Gutena tabs and want to continue using them.
Sorry for the delay in responding – Thanksgiving vacation.
Attached is a screen recording showing what happens.
I am on WP v 6.9 and Gutena tabs 1.0.8

I am also having this problem. I cannot edit the tabs as it will not display. I tried creating a new page with gutena tabs. It lets me put the widget on the page but as soon as I choose a Tabs Style, it gives me an error.
If I can’t edit my tabs, I will need to find another tab plug-in 🙁
