demo.eism.net and www.unique-gifts-jewelry.com are using a SEFU/SEO module that is preventing the ipn_main_handler.php file from being allowed to execute properly.

Try turning off the URL-modifying modules and remove the related .htaccess rewrite rules, and then try testing the PayPal module

I have turned off Ultimate SEO module and replaced .htaccess file with a blank one on http://demo.eism.net/. I am still getting a blank screen:

The requested URL /ipn_main_handler.php&type=ec was not found on this server.

Please help.
