now fixed, Website breaks when the browser window has a width > 1280

EDIT: now fixed don't know how to close this

If the browser windows a width of >= 1280 then the Burger-Menu icon disappears and all the entries are dumped into the main window, obfuscating the whole page.

The origin of the error might well be in the fact that the menu-levels are broken for some reason. Meaning there's no sub-menus but all menu-entries are dumped into the top-level

Attached is a screenshot of the issue (can't be scrolled past)
