I use the mega menu from the Engine Theme. If i try to add categories to that menu I see a part of the menu with an error: undefined, raw value = 1115 fin (please click on tab "Ola Exclusive") See attachment.
I dont know how to fix that. Can You give ma hint ? I use Engine 1.4

Completely disable all of your plugins, then re-download a new copy of the theme from ThemeForest and overwrite all of your current theme files on your server with a fresh copy and see if that fixes the issue. You won't lose any content or settings since those are stored in the database, but if you have made any changes directly to any of the theme code then you should make a backup of your current theme files so you don't lose your changes.
Thank You. It helped.
