Changes to PayPal Recently

[shuban]

Recently, when people checkout via PayPal, it doesn't activate the group membership (since last week actually).

Have there been any prominent changes from PayPal that need updating here?

I am not aware of of any check the ipn script if you visit if it throws an error.

Do you see the transaction in the logs in the mod area.

No they aren't recorded either.

Could you check @ your end if things are working?

I use similar scripts on my sites. haven't had an order today. But will keep watch.
Visit your ipn.php script and see if it works/doesn't throw an error.
