Hi guys! Strange as it may seem, but all options are gone in the theme customizer except widgets. I have other projects running GP Premium on the same virtual hosting with WP 5.6 with no problem. All the plugins that may interfere are disabled. Have you seen something like that before and could you please help me to figure it out? 🙂
It worked in private mode in Firefox only. Completed some housekeeping with the browser. Everything is alright now. Sorry for bothering you with trifles :-). Didn’t know it could be Firefox thing.
