I'm running CIVICRM (4.6.9) on a drupal 7 (current version) installation. I understand from my client (and I have not been able to duplicate this as it works fine at my end) that several of our participants are unable to complete registration (via Paypal) when they receive their email notification of being moved to "pending from waitlist." I'm trying to find out what participants are doing in case that may be the issue, but since it's consistent among 3 so far, am assuming the problem is real.
We don't use scripts or cron for this (or any other function in CIVICRM) - we change participants' status by editing it from within the participant listings.
Increasing the size of the allowable number of participants from 20 to 100, for example, does not change the "event full" status of an event either even though there are no where near that many registrants, regardless of status. Participants are still told the event is full and added to the waitlist when they register. Is this because there are still waitlist entries outstanding, or is it some sort of problem with CIVICRM?
