I'm having some problems with Paypal Standards. I was originally getting an error #40710 that my return URL was no good, so I disabled Auto return in paypal. Now I am getting this error: Sending a relative URL to PayPalIPN is erroneous. Please make your resource URL (in Administer » System Settings » Resource URLs ) complete. I even disabled the IPN feature in paypal but still get the error and unable to make a donation through paypal.
How do I get Auto Return and IPN features working?
