Menus Not Working

I guess I didn’t notice that my menus, located just below the header image are not working. It was just recently brought to my attention and I am working on resolving it. I updated the theme (to Twenty Ten 1.3) I use and it must had modified some code that does not allow these pages to pull up correctly. The drop down menus seem to work, but all of those links open to empty pages. I am currently inquiring about the problem on the WordPress.org Support Forums. So far, I have not received any information that provides me with a reason why these pages (and links) are not working. I did attempt to update the theme to Twenty Eleven 1.3, but the problem remained. Thankfully the blog posts still working, hopefully I will have full functionality back on the site in the next day or so.
