When using Q&A, after a user logs in, the menu items seem to redirect to the wrong pages

When using Q&A, after a user logs in, the menu items seem to redirect to the wrong pages. In the menu I have a Q&A and My Second Question. When no user is logged in, the Q&A opens the questions page, and the My Second Question opens a specific question. After a user is logged in, these menu options don't work. This happens on firefox. Seems ok on Safari.

Thanks
