I didn't fix anything and it sounds like it was something that is related to the hosting company this website is on. I never experienced it, been to busy sorting out my PC that decided to get really screwed up, actually I had a lucky escape.
I backup my PC, maybe foolishly, I think every 6 months. A couple of days ago I suddenly had a strong gut feeling I should backup my PC, so I did. The NEXT DAY, my hard drive severly corrupts to the extend that nothing was recoverable (with my knowledge). So, lesson here is following your gut might just save you from disaster. Some might say this is coincedance but this sort of thing has happened before so I don't know what it is
