I have a Premium Membership set up to renew annually.  Everyone who is getting the renewal notice is having trouble.  I have used the same PayPal account for over 10 years, nothing there has changed.  I have not made any changes to the membership since I set it up last year.

Did I set something up wrong?

Here is a reply from one member:

Yesterday I received an email renewal notice for the premium membership but the paypal wouldn't go though. If I try to do it though the forum store instead of the email, I get a notice that I'm already a member and can't do it twice. Paypal says nothing went though. Is this something on my end or the site's?

I think paypal is making some changes to not accept IPN any more - dont quote me - just something you could investigate
