Coding error: isteacher() should not be used without a valid course id as argument. Please notify a developer.
got the above error when I was (erm) mucking about to see if I could login directly to moodle despite requiring that users login via portal site, i.e. authentication requires external db authentication.
Anyway I'm -now - running v1.4.4 and this error appeared on http://www.lvc.org/courses/login/index.php page.
