paypal and hosting

Hi,

I have hooked up a website with Palpal on my home server.
It is working fine. I get "FAIL" or "SUCCESS" response from PayPal.
But when I put the exact same code on hosting company (dynonames.com). I get empty response from Paypal.

Paypal says talk to your hosting company, hosting company says everthing is fine on our side talk to PayPal.

I wonder if anyone has any idea why I am having this problem?

Thanks

Can you provide a link or something so we can all test it?

I'd recommend checking the code.. making sure it submits to the right site.. or else maybe the server doesn't support the coding language?

Would be a good idea to post the link(s) as monsterhosting has said above..

i don't think you can test unless you have account on PayPal sandbox, which is their testing inviorment.

Anyway link for Host
