I find I can approve and unblock users from the CB User Manager list but if I open a user I can't do any changes. Oddly enough there are 3 users (myself and 2 others) I am able to edit, but anything after 7-14-12 I can't do anything with.

Getting very discouraged at this point. I've disabled all sorts of components, had my hosting company look at it and nothing. It's obvious to me this is a CB issue.

Please PM me backend superadmin access and I will take a look.

I took a quick look.

I remember some issues reported because of mailchimp script and i see you are using this - kyle will have to take a look at this tomorrow.

Have reviewed your install and it's due to 3rd party Joomla system plugin "System - joomlamailer MailChimp Signup". I've disabled it and issue appears resolved. Please also confirm if is working fine for you now. I am assuming there's perhaps an error or something of the sort in the plugin resulting in the redirect, but can't say specifically; you'll need to contact mailchimp or whoever developed the plugin for further support if you intended to continue using it.
