On the back end, when I go into a user detail and make even a minor change and try to save it, the checker for the email and the username run. The user name appears to run succesfully, but the email checker just keeps going, eventually displaying the word "error" and then the page disappears ending in a http 500 error. The biggest issue is that none of the changes I make are saved.
This behavior also occurs if user detail changes are made on the front end.
I made two changes. I upgraded from cb 1.3.1 to cb 1.4 and I installed the FaceBook plugin.
Appreciate all the help I can get.
