I've tried osCommerce on my site. It was all working great but when I tried to do checkout a message appear that said that "The connection refused...".

Does anybody know what's the solution to this problem?
Did anybody used it before?

Thanks for all users who answers... :)

Was there anything further to that error? It might have simply been a timeout issue with mySQL on the hosting server.

Thanks for that fast comment...

Anyway I won't take the risk of managing my own store...
Better assist some company...

Thanks anyway...
