Of the browsers I had access to, it did display fine. Safari was the only main browser I couldn't view it in as I don't have a Mac. I have made a change to the header to hopefully solve the issue. Can you confirm that it is now not overlaying the logo?
Thanks very much for your help Mr.Panos. Neither myself or Fowler use a Mac, so we appreciate you letting us know about the issue and for your patience with helping us resolve it.
