wierd problems with Zencart

[Andy-C27]

Hi All old my old account has been lost/forgotten as it has been a while since my last visit

But my weird issue has started today..
Firstly I saw a image that was not showing on my website which I thought was weird, so I went into admin to reload it but lo and behold it just wouldn't load the image again (tried multiply times with new an old products) ..
Another an hour later I came back to try again and lo and behold it uploaded ??? .great I though now I can add the 1 product I deleted .reloaded fine as well but then went to find it it is missing on the website but can edit product in admin ????
link is http: // pewterworld.co.uk/Jewellery/Cufflinks/Canines/PoodlePewterCufflinks (just remove spaces) or search poodle

I have a load of addons and am using 1.5.1
Have uploaded a screen shot of all my add ons as it is easier to see what I have ... Been uploading products since Christmas with no problems except today..
The only thing I have changed in the past week or so is the bread crumbs file which I did last night ..put the right 1 back today

Any help appreciated
