I have a typo3 project which uses mmenu in order to create a hamburger menu after a certain screen-size (smaller than 980px).
mmenu v8.5 works perfectly, but with mmenu v9.3, the additional menu (which is supposed to be hidden) is visible in all screen-sizes and also all the menus (nav menu at the top and the mmenu on the left) are unclickable. The left menu covers half the screen on the left.
I have unfortunately no error message. The only difference, I noticed with the old version is: the second menu has an id of mm-my-menu in the working old version but it is mm-clone-my-menu in the broken menu.
I changed the attributes on inspect screen in order to find out the problem but it changes nothing. I'm new with TYPO3 and I'll be really thankful after any help or suggestion.
