I've used prestashop now for 4 years, and i'm still on version 1.3, so i'm updating my shop, i have everything set and have copied the database to the new 1.5 version, in a sub-folder on the server, the problem is that i can't login, even though the password and email is correct (still works on the old version) and the main page is blank, my thinking is that the database still thinks it's working from url.co.uk not url.co.uk/newsite? have i missed something by transfering the whole database across?
