When enabling Limit User Items in osclass payments plugin, the user/items dashboard is breaking when you are looking from different screens(press ctrl+zoom in scroll) It happens because of the message that says Premium membership and account limit its also displaying behind the user menu

You will have to provide URL and screenshot.

You have both, theme and the plugin you really cant try it on your setup? they dont break by default with no modifications. User menu in beta theme is always on top of a panel with a width of 100%

That does not look like as image & url.
