Email Confirmation link throws a fatal error
I'm running a new Vanilla 2.2 setup. I installed fresh and imported data from my old phpBB forum.
In the registration settings I've set the method to "Basic" and checked the box for "Require users to confirm their email addresses (recommended)"
However, when a new user tries to click on the confirmation link that is emailed to them, they get sent to the "Something has gone wrong." page.
I turned on debug, and got the error "Fatal Error in PHP.trigger_error();"
I can't figure out what's going on. Can anyone help me out?
