I'm only posting this as I've been trying to solve this problem for 6 hours and trawled this forum for answers, tried everything that I found and still got nowhere.
So, in case this happens to someone else in the future, here's the nature of my problem.
Problem: My homepage was blank, no other templates worked, and I could get into admin fine. Permissions and ownership of the files was all OK and it was re-uploaded several times.
Solution: My problem was with GK5, or more specifically my unmanaged box and the fact I'd not installed the cURL and GD libraries. Once they were installed, it was perfect.
The template, for the record, was Creativity.
Thanks for such superb templates, they're sooo much better than who I suspect are your 2 largest competitors (who I probably shouldn't mention RT/YT) and seem to be the best Joomla templates I've had the fortune of using. Keep it up.
