UberMenu stylesheets disabled

3

If the basic.css file has been disabled in the Control Panel, the menu will not function properly if the styles have not been included elsewhere.

The Problem

The ubermenu.css file (basic.css in UberMenu 2), which contains all of UberMenu’s structural styles (the code that makes the menu an mega menu), has been disabled.

The Solution

UberMenu 3

Re-enable the ubermenu.css in the UberMenu Control Panel > General Settings > Assets > Load UberMenu Core Layout

UberMenu 2

Re-enable the basic.css in the UberMenu Control Panel > Advanced Settings > Include basic.css
