Clicking on "questions" in askfedora should take you to the all page.

Click "unanswered" to see all the unanswered questions.
Now click on "questions" and you are at http://ask.fedoraproject.org/questions/

Expected: Clicking on "questions" from any where in the site should display all the questions.

It is most likely due to the way caching is set up on ask.fedoraproject.org. This site and askfedora run the same software (maybe versions are a little different) and here we don't have this issue.

Some days ago we resolved one particularly noticeable caching issue as described here http://askbot.org/en/question/631/askbot-and-memcached. Is this issue different? Do you have changes in the puppet deployment script where those middlewares are removed (as shown in the linked post)?
