Picking any tag, for example, 'c' then http://stackoverflow.com/questions/tagged/c
returns a result page with 0 results (and sidebar, header). This is the same for every tag I've tried.
Platfor: Firefox 3.0.11 on Mac OS X.
How I reproduced:
I did this:
- I clicked on one of the tabs - Questions
- I clicked on a tag 'svn' in the main list of questions
- I got a 0 search result
The title of the final page says "Bounty 'svn' Questions" so some session state is clearly confused and all my tag searches are stuck onto questions with bounties only.
Result: not a bug, but it is confusing (see the accepted answer), but you have to click on the lower of the two set of tabs - active / featured / hot / .. in order to get unstuck.
