I am urgently trying to create an off canvas menu, with widgets (and with 2 test menu items too) but cannot get it to work. There is nothing visible, no hamburger or overlay, even when set to overlay for all screens.
I confirm that the GP theme and plugin are up to date. Though I am using Local by Flywheel, on my 2017 Mac, I have created a small test menu in the identical online site (url below) for you to see. I confirm I have cleared the browser cache and deactivated a cache plugin. There is a cache on the hosting, but if that was the problem it would work locally on my computer, and it doesn’t. I confirm the menu is allocated to the Off Canvas in menus. GP MenuPlus is activated. As you’ll see, I’m not otherwise using a menu yet, just a widget sidebar.
