Hi all,
I'm running moodle 2.3+ stable (installed about a week ago). I installed the moodle freshly, than imported two courses (with users, grades, etc). Now, when a user tries to register, they get the "sorry, you may not use this page" error, and a link to the notlocalisederrormessage error page: http://docs.moodle.org/23/en/error/moodle/notlocalisederrormessage.
So, I looked in the code, and the error is in login/signup.php, lines 31-33:
if (empty($CFG->registerauth)) {
print_error('notlocalisederrormessage', 'error', '', 'Sorry, you may not use this page.');
}
a var_dump of $CFG shows that registerauth is an empty string.
