Hi,
The plugin seems to be updated (2.8 version).
when I dis-active the menu (or the plugin), the scroll right/ left problem disappear.
The only horizontal element is the sticky-menu of the plugin, with the hamburger icon and the text
“???? ???????”
that now can be found on the top leff of the screen instead of in the middle.
when the menu behave as it suppose, it’s loog great, like that –
