Setting VB up on test domain

[cdguk]

I would like to replicate my vBulletin install to a test domain so that we can develop a new skin for it before we go live but I'm having trouble.

I've copied the files across and the DB.

I have changed the site URL and the domain under HTTP/Cookies in the settings table.

However, it's still redirecting me to the live site on the frontend and will not allow me ot login to the admin panel (it redirects me back to the login form).

I have checked the .htaccess file too.

I can't seem to figure it out?

you need to install it first make a folder called test upload all the files install so it will look like
