The scheduler could also be blocked due to unfinished upgrades; check the [tt]upgrader.php[/tt] and make sure you ran the database upgrade if necessary.
 WRONG_JOIN_MODULE_PERMISSIONS=The test account does not have access to the join module. This implies members might not be able to re-agree to the rules (Terms of Service) if you require acceptance and you change the declarations (effectively locking them out of their account). You should fix this immediately under the Admin Zone > Security > Permissions tree editor (also check Match-key page restrictions if the addon is installed). The only group that can safely be denied is guests (if you want to disallow account registrations).
