Wordpress adding 000 to beginning of posts

So my sideline company website has needed some work to get it up and running properly and I'm getting there in between my day job and a very playful 2 year old but I'm having some peculiar things happen with my pages.

I've got Pages which are my products and the main website and am using Posts for the news/blog part. Problem is when I display the Posts in the sidebar or on a page it seems to add three zeros to the beginning of the text. I've had a quick look at the code and can't see anything obvious and from where I am at the moment I have limited access to the server to see what's stored in the actual MySQL DB but when I edit the post they don't show and it's every post that gets it added.

You can see what I mean here : http://www.cassycastles.co.uk/the-bouncy-castle-blog/

Any of you out there have any ideas what I can do? I have a vague memory of fixing this before but I can't honestly remember what I did.
