I had an incorrect IPN URL in my paypal account and this seemed to be causing members to "expire" because when a payment (paypalstandard) was made, the IPN was wrong and thus not inform the site the user should remain active. Members who had funds paid through paypal then had no access to the site. As a solution, I would have to manually add them to the appropriate membership. I now have the proper URL set up in my IPN settings and it seems that these members are now being charged on both their initial setup AND when they were manually added. So my question is is this what is supposed to be happening? So when I manually add someone to a membership who is set up as a recurring payee, is this supposed to charge them monthly as well? Is this why they are all being double invoiced and double paying? What should I do to fix this?
