From MoodleDocs

I have not been able to get auto enroll for courses using PayPal in Moodle 2.3 or 2.4. I get up to the following message:

Thank you for your payment! Unfortunately your payment has not yet been fully processed, and you are not yet registered to enter the course "Test1". Please try continuing to the course in a few seconds, but if you continue to have trouble then please alert the Teacher or the site administrator

Is there a way around this?

Thank you. Nellie
