I have wooframework 5.5.5 and mystile 1.2.7 and I am having the same problem, but the other way around: I don’t want to open in Lightbox (w. the rounded corners), but whatever I check it persists opening in Lightbox. I even changed it to ‘no’ in the database but that doesn’t help either.
I have the same problem with the option of the product thumbnail aligned ‘right’ – it keeps aligning left.
Exactly the same problem here.
I just tested it online and there it works as it should. Resolved!
I had the same problem, that is: the Tinymce buttons totally disappeared in the ‘Editor’ user role. I used Safari. When I switched to Firefox the buttons showed up as usual. So try it with another browser.
