About two weeks ago, I got a report from a customer who said they were having problem with their Shopping Cart not going to paypal correctly. It had been working fine for over a year so I did some checking and paypal has made some changes that affect a lot of sites. The specific error is 500 Internal Server Error.
- I upgraded his cart to the latest version (which wasn't listed with the project on the DNN site), that didn't work.
- I tried changing both url's to https://www.paypal.com/cgi-bin/webscr as suggested on s post, that didn't work.
- I tried using this method http://blogs.snapsis.com/PermaLink,...cc8eb.aspx to place a simple buy now button on the site, that didn't work either.
- I finally put the code on a plain html page and that works fine so I don't think it's paypal at this point and think its DNN.
Is anyone else having problems? I can't believe I can't find more post or anything on this as I don't think this is an isolated event. I have tested this on several sites and get the same error on all. Any help or insight would be greatly appreciated.
