some products are not displayed

[zeisch]

Hi
I checked the forum about my issue but I can not find a solution.
Sometimes products are not displayed within a category even though in the backend they are visible within this category. Sometimes they are there.
The screenshot of the backend is attached. Here is the link to the frontpage. To me it looks like it is a browser cache issue but that is not the reason since I have tested it with multiple browsers.

Do you think it could be because of the shop which was originally set up with Joomla 1.5. and then updated to 2.5?
I would be happy if someone could help me with that.
Kind regards,
Jonas

Comparing your backend screenshot with the your 'Beamer/Leinwand' category in the frontend, the products are identical. I see 13 products in the backend and also 13 in the frontend. The last Beamer on page 1 is identical with the first one on page 2, which might be added there to evenly fill the product rows.
