Nant,
I haven't changed any permissions lately. Registration Access Level is "Public".
Now, I cannot even login from the home page and receive the same error. (I can't login in using a Admin account - or even normally registered user.)
Interestingly enough, when I try to login through a menu link to the Login/Logout User Menu any user can login. (The original Joomla login/lout link)
planethop.com/index.php?option=com_user&view=login
My registration and login issues happen when it is done through the CB Login Module, which is published on the home page.

PS: I have CB Auto Actions installed, with a re-direct on login to the user profile for Registered users. Even if I disable this redirect and Plugin, there is no change.
You have registered on my site before as "nant", so you may want to see for yourself.
If you need backend access, I can PM you.
The only major change that I have done recently is upgrade from CB 1.7 to CB 1.8. Did not have these issues before the upgrade.
This issue has become a MASSIVE problem for me; hope you can help me resolve it.
