Undefined index: member_groups

SMF 2.1.2

So I cleared my browser history and cache this morning and just now logged back into my forum and get this error message:

Error
Type of error

What does it mean and how can I fix it?

Thanks,

Undefined index: member_groups

This error ususally happens when php tries to access an undefined index of an array.

Have you installed any mods lately that have to do with group management?

I have a lot of mods installed. I redone my site and reinstalled the same mods I had before but no new mods and I didn't get that error before.

Here is the long list of mods I have installed...lol!

You cannot view this attachment.

I have logged out and logged back in and don't get that error. Seems to only happen after I clear my cache and log in.

It is weird that you start at edit member group after a login.

What happens if you go to that page again or tries to edit a member group?
https://*******.com/?action=admin;area=membergroups;sa=edit;group=9

Nothing, just went there to edit and clicked save and no errors. Very weird indeed...I can't reproduce the error!
