Greeting again, After I have asked my current host company to transfer all my data to its server and having changed the nameserver i am having a blank page for my subdomain site http://forum.movizddl.com The main url is working http://movizddl.com but not the sbdomain! Any help please
Have you set up your subdomain? If you're using cPanel, login and head over to "Subdomain" on the Domains tab and create the subdomain. Edit: Also, what forum script are you using?
Both forum.movizddl.com and movizddl.com have the same IP. So I think it's not the nameserver problem.
maybe database connection not perfect.... sometime...database connection setting change when export to another hosting provider
