Can you explain your file structure?

 

Make sure the step1 is done correctly.

 

If your forum is installed under a virtual directory, like abc.com/forums, you should copy files to the virtual directory (abc.com/forums/...).

If your forum is located at the root of your subdomain, like forums.abc.com, you should copy files to the root of your subdomain (forums.abc.com/...).

If your forum is located at the root of your domain, like abc.com, you should copy files to the root of your domain (abc.com/...).
