I have this new Magento installation (i've used the downloader from Magento page, and installed the community 22.214.171.124 version), wich don't display product pages, just throw 404 error page. I've created just one for reference, but it just doesn't work.
-> The product stock is fine (100 itens / in stock); -> "Use Web Server Rewrites" is off; -> Already truncated the core_url_rewrite table (like here); -> The error doesn't happen "sometimes" (like here); -> Already cleared var/session and var/cache.
Here is my application. It's a catalog page, click in the product link and see the error.
