I have lost my product descriptions, the product listings are ok but when you click on "more information" I get the zencart 404 message and site map.

In administrator mode I can see all of the products but get a server 404 error, what is interesting is it seems that my zen cart isn't creating the urls correctly any more this is the server message.

"The requested URL /store/admin/.php was not found on this server."

note the .php ??? I have checked mysql and the product table and content is still there.

Does anyone have a suggestion?
