I don't know what's happening, but since I come using Magento 1.8, simply I'm not able to reindex, because after a reindex process, the products go away as if by magic. Anything I do, such as repair db, reindex through ssh or other else task, is not effective in order to show the catalog again.
Is there some reported bug about that? I've tried to perform a lot of things I've found on internet, however anything has worked. So, if I wanna keep products on their right places, I just can't reindex, and it's not normal, isn't it?
Any help is very welcome!! Thanks.
