Forum Problem with making test site
 

Hello,

I want to upgrade to VB4 but I have problem. I made new database for testing, restore current one to it and upload copy of my live forum ( I made a subdomain ). Test site is working but I can't log in. When I try to do that it redirect me to live site for 2 seconds and bring me back to test one but still not loged in. I have change database name, user name , password ans cookie prefix and also disabled all hooks in config.php . I have also try do delete all cookies and even to install new browser which I never use but problem is still there.
Also, everywhere I click link me to live site. All links are same as on live site.

Thanks
