products disappeared RESOLVED

I had several products displaying properly but when I added a new product, and clicked on the product description under the pic, this is now the only product showing and all other products have now gone from display. There appears to to be no difference as to how this new product and the others are set up

The problem appears to be a cache issue. When I click on a product image it goes to the description etc as expected. However, when this page is left or the site reloaded, it only displays the particular product that was previously selected - all other products are no longer visable, no matter what browser I use. As this will be an issue with users, I need to find a way to overcome this. Instructing the user to dump their cache is not the way to go. Have I missed a step in configuration that resolves this?
