Picturtes and info don't show up on my website

I have ZenCart 1.5.1. and Firefox. I can enter all my info for New Category, then enter New Products. Everything seams to be OK on the ZenCart site. When I go to my website the new category shows up with the number of new products the I put in. When I open that category no new products show up. I used ZenCart to put new products on my website last week and that worked OK, but I used the wrong info so I deleted everything Since than I have not been able to put products on the website. I must have messed up something. Any ideas??
Thank You

How were products entered? How were they deleted?

Other questions that would help support a solution would be to answer questions in the Posting Tips that appear above the entry of posts... For example, is the ZC 1.5.1 version operating on your site an upgrade? From what version was it upgraded? What version of PHP is on the system? If it was an upgrade, how was it upgraded? Any debug logs? What plugins have been installed, etc....
