After numerous tests, buttons created by PayPal worked for our initial subscriptions but the S2Member button did not. S2Member buttons gave me "ERROR: Unable to verify $_SERVER[“HTTP_HOST”]. After learning that I had to do the following, the PayPal created buttons worked:
PayPal payment button creation in the PayPal account (tools, all tools, PayPal Buttons (open), View your saved buttons)
There are several variables that must be added through Step 3: Customize advanced features (optional).
- Item ID next to the Item Name must be “1” for subscription level 1.
- Add the following variables to Step 3: Customize advanced features (optional)
custom=mountainmeadowquilters.org
notify_url=http://mountainmeadowquilters.org/?s2member_paypal_notify=1
rm=2
Is there a workaround for the subscription modification button in PayPal for renewals? I’m getting the “PayPal” message “Things don’t appear to be working at the moment. Please try again later.”
Are none of the S2Member PayPal buttons working? I’m using the S2Member Pro with PayPal Standard but I also tried the Pro Forms while eliminating all payments methods other than PayPal.
