I'm getting these script errors on my shared hosting site (Drundo). So I suspect that I need to enable (or at least check) "webpermission".For future reference, IPN works in medium trust. If you have straight medium trust, the payment will work but the ProcessPayPal.ashx script will give errors. You have to have medium trust + webpermission otherwise your customers will see an error upon attempting to return to the store. (It is common practice for hosting companies to enable webpermission.)
Will a tech support person (at the hosting company) know what "webpermissions" means when I ask them to enable it?
Thanks,
