UPDATE **** i forgot to update the question. Thought i would at least now post the solution. After reading on MKportal website, they say that there are 2 files named "tpl_main.php" one is a bak file. Apparently most things that go wrong with site, so long as you have a decent copy of this as a back up file on the server, you can replace the old one. Not sure if it will work on all probelms, but seemed to work for me. Thanks for you help though. Much appreciated
