Hi
it seems that there is currently a compatibility issue with autoptimize 2.9.5.1 and GP 3.1.1/ GP Premium 2.1.1
If you turn on the off canvas panel, the menu is always shown on the bottom of the page – even if the menu is closed. if you try to open the menu, it is not displayed.
I’m not sure if this is related to you or to autoptimize. Could you have a look at this?
Thanks
it will be related to Autoptimize and how it is combining and minifying the CSS on your site. Which will be different from one site to another.
Best to ask Autoptimize support for some input
