[analyzer] Website menus?

Does anybody see any obvious reasons why the top menu in clang-analyzer.llvm.org is broken on all pages except index.html? Eg. http://clang-analyzer.llvm.org/scan-build.html - I'm sure it worked a little while ago.

The sources for the website are in clang/www/analyzer (i.e. clang/www/analyzer at master · llvm-mirror/clang · GitHub) - so it's an SSI #include directive at the top of every page, but for some reason it only works on index.html. I don't see what's broken in the sources, might it be a server issue?
