Hello Leo, thanks, I did the double check before. Now I deactivated “cache enabler”, that didn’t help, then I deactiveted “autoptimize” and that was it. It seems that “Autoptimize” stops the off-canvas-menu. Reactivating “Cache enabler” didn’t hurt, but reactivating “Autoptimize” made the off-canvas-menu disappear again. What in the settings of Autoptimize do I need to change? I have a very simple autoptimize configuration, only the standards….
Thanks for the solution. Now I will have to find out how I need to configure Autoptimize.
