I have a website http://www.specialeditionchocolate.co.uk built in OC v 1.4.9.? and it has been running fine for months. I created a staff user who now adds products to the site and he has tinkered with category names. All of a sudden the site will not load at all. Or the admin.
I asked him what he's done (via email) and he said "From what I can remember the last changes I made were:-
1. I added 2 products, one to the Easter category and the other to both Easter and Animal categories.
2. I added additional picture to the Victorian button products (in all 3 flavours).
3. I changed the main image of the 3pack bar entries (in all 3 flavours).
When I'm changing or adding products I always have the web page open in another tab. So when I have 'enabled' the changes I can just refresh the page so I can see that the changes have been made and what it actually looks like on the site. Everything seemed ok last time I was on.
The last time I rearranged the order of the categories was about 3-4 weeks ago. Many people made purchases since then
That's all I can think of at the moment"
I have looked at the error.txt file but it doesn't mean much to me

Any guru advice?
