More than likely it's your hosting that is giving you the problems. I see you posted in most of the other threads about this script, so you've read all that I've read on this forum about this same issue, and honestly I can't think of anything else that could be the problem. I don't use free hosting, and I have installed the script on two different domains on two different paid hosts with no problems. The script I used is the one MP3Mage posted, which I believe is the link I directed you to.

ohh thanks booman so the problem is the host,therefore, it is necessary that I use a paying hosting to have the script installed without any problem because , I have follwing all steps of installation,i will try it in any sheap hosting to test him,after i will decide thanks booman for your help
