paypal checkout internal server error

[transtor]

You'll have to contact your hosting company to find out what's causing the "internal server error" ... because it's most likely being triggered BY your server ... and their tech support has access to the logs which explain what "rules" are triggering the error message.

Thanks!

I contacted the godaddy server rep just now. He told me that everything including checkout using paypal is OK at his end.
He suggested us to check the codes, the links connecting paypal, ourwebsite and the server.

All your answers are still welcomed!

Thanks!
