Oscommerce 2.3 getting relay response or receipt link URL is invalid.

[mark3500]

The Authorize.NET SIM mosule was working great with oscommerce 2.2 but now I am getting this error after upgrading to 2.3.

NO settings have been changed at Authorize.NET:

The following errors have occurred.(14) The referrer, relay response or receipt link URL is invalid.

Do I need to dig into my Authorize.NET SIM php file to make sure the link is correct. here is what it says:

tep_draw_hidden_field('x_relay_response', 'TRUE') .

tep_draw_hidden_field('x_relay_url', tep_href_link(FILENAME_CHECKOUT_PROCESS, '', 'SSL', false)) .

Thanks

This error can be either due to an invalid URL being passed, or to a URL being passed that does not match what is specified in your account settings.  When you add a URL to your account's list of referrer/response urls, it creates a sort of relay response URL whitelist.  It is possible that in the past you added the relay response URL for oscommerce 2.2 and that URL has changed for 2.3.
