Can not edit Custom Field Groups

Hello,

I have been working on making Custom groups for custom fields.
I was getting errors when adding too many fields – so I split this up into Groups.

Everything has been going well- but now I am not able to edit ANY of the groups.

Attached are the screen shots — and also I checked the JavaScript error log – and message is attached.

Thanks, Not sure what to do — I spent all day setting this up, and got categories ready also.

Image is front – and error I get when I click on Edit of any group

Thanks,

Kristen
