Can you login to Trac, check to make sure that your email address is listed in your account, and then try sending another Verification Email? http://dev.haiku-os.org/verify_email
I just logged out, logged back in, checked that my email is entered correctly, visited your link, then clicked “Resend Email”. Unfortunately, I got the same error:
Trac detected an internal error: UndefinedError: “projec” not defined
I have tried deleting my account and reregistering, nothing worked
EDIT: The same error appeared upon logging in for the first time, I assume when Trac was supposed to send me the automatic verification email.
