imported site from where? and the dynamic content or files might be coming from a database.
imported from a clients host.All files are PHP and all links are relative.
do you have a server and database set up locally? if not then you would not be able to view pages with dynamic content
I set the server through Site Setup
Connect using Local/Network
Server Folder is correct
Web URL is blank
Server Model is PHP MySQL
and have Remote and Testing checked.
