BuddyPress.org

Hi can anyone help I have a problem with the extended base group profile fields on 2 profiles the profile field boxes are fine and display full length but on the newest members profile fields seem to be displaying in a small box and aligned over to the right of the page not as wide as my admin profile fields or one of the other user profiles iv’e tried a search and found a code to over ride the CSS but it hasn’t worked i’m using the latest version of BuddyPress and my website is http://thattuneuk.com I hope someone knows how to fix this problem as iv’e been racking my brains for a couple of days trying to sort it out.
