I've just created a new website with a fresh install of Wordpress with no plugins. I installed the latest version of DMS and the site breaks when I'm logged in (I've attached a screenshot) (only in Chrome). It looks fine when I'm logged out or when I'm using Firefox (whether I'm logged in or not). I tried changing the user agent in Firefox so it thinks it's Chrome, and the same thing happens. I also tried using an older version of DMS and it's the same thing. I have DMS installed on another site and it works just fine.
Any idea what's wrong?
