thank you

Did you enable virtual hosts (wildcard subdomains) in Apache first?

hi
can you tell me how can i do it ?
step by step
thnk you

Did you read the directions that were in the main directory of the package when you extracted it?

It explains it there, and then gives a link to more information.

If you're on a shared hosting account, your host will have to make the edits. Providing they are willing to do it.
