HI
I am having the same problem. The theme settings menu has just disappeared – I am trying to update the cookie pop up and some background colour changes- I can’t access the theme settings at all. The theme settings appear in the top menu as a drop down but when I click on one of the options,, it takes me to the general setting page again with no menu.

I have gone into multiple browsers, emptied my cache, used incognito- everything as suggested but it doesn’t appear.

Thanks!!!
