Ok. Didn't know that. I downloaded that script from (a kind of) Php Tutorial/Resource web site. Thanks for the reply. (I have another hosting plan in Godaddy which I tested that script and as it was working fine I didn't think there would be a problem.)
I had this warning: "...Violation of x10hosting's terms of service. Details: nulled scripts are prohibited on x10hosting's servers..."
I was trying to use a script which was working on "Godaddy Hosting" without any problems before. I don't understand why it's violating your terms of service...
