Product View Page won't load after 22.214.171.124 upgrade
After upgrading from Magento ver. 126.96.36.199 to Magento ver. 188.8.131.52 every time I click any product link/url the product view page doesnt load and it re-routes to the HOME page as set for 404 rerouting. All my products are showing in the catalog listing and everywhere else however on clicking none open the product page.
I have tried everything, cleared out all products and reimported them again, reindexed, cleared cache, truncated core_url_rewrites and set file and folder permissions. I have tried base, default, custom, and rwd design themes and the loading issue is the same on all.
