Thanks again kuroi for you reply much appreciated :)

I managed to modify the tpl_header.php file so that my links in the header are once again active, however that little red 'x' has popped up again and I have followed your previous instructions but still cannot get rid of it, I realise this is probably an easy fix and apologise for asking repetitive questions but Im very confused by it all and really dont know where I have gone wrong.

Once again any help or advice would be fantastic, hope you all have a great day!
