All products that I added in my admin page displaying as out stock in my store even they're not (in Inventory the quantity is superior to 0 by far, the Stock Availability option is in Stock and this Visibilily is 'Catalog, Search').
And when I open the product page in my store it's 404 not found error
I tried to refresh cache and reindex data but always the same problem
Is there a solution to that problem ?
ps: I'm using Magento 1.8.1 CE
Please confirm that you have set the proper quantity and related field settings in "Inventory" section of the product. And also check the settings into the system->confuration about the display the products.
I confirm that all quantities in inventory are superior to 0 and for displaying products in system -> configuration is enabled
