New products not showing

Hi,
I found at an hour ago that some products in my shop aren't visible. I saw that the problem is only in those categories, where I have alot of products.

So: when I click on a category, this category is empty (like this: http://www.ustvarjalnidotik.si/index.php?main_page=index&cPath=16_59 ) , but when I click on the same site on a manufacturers filter, than I see products (like here: http://www.ustvarjalnidotik.si/index.php?main_page=index&cPath=16_59&sort=20a&filter_id=18 )
Where is the problem?
thank you

You might also look in /cache ... assuming you are using Zen Cart v1.3.9 as the debug logs may help ...

If using old, out dated versions of Zen Cart, you might get the Debug Tool from the Free Software Add Ons ...
