XF 1.2 Cannot register after upgrade


Well-known member
Just upgraded and things seem to be working fine.
No server errors.

I am allowing new registrations, but when I try to register a new account it says:

Please correct the following errors:

  1. Something went wrong. Please try again or contact the administrator.
I also noticed that no other users have registered.

Can anyone tell me where such errors are logged and where to fix?
