When I attempted to use the PayPal Test account I created, PayPal did not recognize that seller account. Here is the error I am getting when I clicked on the Return to merchant button...
Fatal error: Call to undefined function mosgetparam() in /www/local/home/user1/domain.cc/components/com_dtdonate/dtdonate.php on line 237
The initial problem was that I had configured DTDonate to use my PayPal Sandbox Test merchant email address, which for some strange reason PayPal did not recognize as a valid address even within the sandbox environment.
I get the same error and am not using the sandbox. If I go ahead with the transaction at paypal the return link works. If I don\'t go ahead with the transaction and click the return link, then it gives me the same error. I\'m using the latest version (bought it yesterday).
