Problems after updating Illdy theme and illdy companion plug-in

Hi moderator!

Hope you’re doing well today as well.

Just found this post on the same problems caused by updating illdy theme and illdy-companion:
https://colorlibsupport.com/t/latest-theme-update-has-screwed-up-theme-customizer-illdy-companion-issues/

Seems there are a lot of people having maior problems with the updates for a while now.
I’ll try some solutions given in this thread, and if they don’t help I’ll ask moderator Laranz for some assistance on finding a solution.

Thanks for you support so far!
