I installed the djmegamenu-module on https://hetnatuurhuis.nl
because I wasn't happy with the standard menu in the template I use (font awesome didn't work). Now I'm getting a warning in the AMP-validator and there is no menu-button on the amp-page. The warning is (on line 101, column 7):"The extension 'amp-accordion extension .js script' was found on this page, but is unused (no 'amp-accordion' tag seen). This may become an error in the future. Debug. Learn more."
I changed the menu-settings in the jamp-plugin (Menu module name = Hoofdmenu, Menu module title = mod_djmegamenu), but maybe I did something wrong?
