All sorted. I was missing some files from wp-admin so uploaded some new ones from WordPress and bingon life is good again. Thanks Clicknathan for taking the time.
Update:
I narrowed it down to overwriting my index.php file so downloaded a new new one from WordPress and uploaded that. My website is back up and running!!
Only one thing though when I try to access my WordPress Dashboard by using http://www.comtech247.co.uk/wp-admin I get a list of files instead of my login page. Any ideas?
Thanks
