Can not access “More Grid Design Options”

Replies: 0

Hi all,

recently I found out, that I am unable to change any option under “More Grid Design Options” in the design customizer.
The option itself is there, just nothing happens when I click on it. It is supposed to expand to some more menus entries but that does not work (it did – somewhen before).
On a mirrored development site (nearly a 1:1 copy, just no SSL) everything works as expected.

Any clues what could block access to this menue?

Thanks,

Thomas
