Hey Frank,
thanks for your quick response. I have a menu, when I deactivate Autoptimize.
So right now, it's deactivated and it's working.
I'm using the same Theme here https://bali-luxury-resort.com and https://bali-luxury-resort.de
On the .com donain I have the same problem, but on the .de Domain it is working...
Best regards and thanks a lot!
Andreas
