Module must be save basic option to param attribute at module_table. And param attribute using type "text". And your product category have too many item. So when you save that, maybe your database overflow, then you can not save basic option.
So please change your type of param attribute to bigger type at module_table.
Hi, I have make som changes in the DB, and I have try many other things w. this module. And I can't still use this bad module!
I have same problem with K2 Mega Menu. When I apply changes in module setting they don't show in front end, they remain the same of installation setting.

Can´t save setting in backend
