Trying to make changes to parameters in a K2 menu item. No matter what I change, as soon as I click save everything goes back to defaults. REALLY annoying, just when I was starting to like K2.

Has anyone got a solution or had this issue?

If the parameters are for multi-category menus and you are only using a single category, then will automatically revert to their default settings.

If that is the case you need to edit the category's settings instead.
