Go to templates and style, click your theme, go to global css, use advanced mode, ctrl+f (wrapper). change the width to what you want

Change the width attribue of he #mbox element in global.css
Hello.
i have changed it and nothing happens.
im using duende version 2 theme.
When I change the width of #mbox in global.css from (now) 70% to for instance 90% with Firebug I see a clear difference.
Perhaps you see no difference (yet) because css is cached. Try a refresh of the page and/or rebuilding caches from AdminCP.
