I upgraded Magento CE from 220.127.116.11 to 18.104.22.168. I followed the knowledge base article on how to upgrade Magento
and believe I did everything correct. However, FishPig WordPress and other free community extensions no longer show up in the Magento Connect list like it used to although they still shows up in the backoffice under configuration and also in the top menu.
What could cause an extension to disappear from Magento Connect after an upgrade but still be installed and working? I have already verified that download/cache.cfg is writable.
