Sorry for the inconvenience. Known Navigation header breakage, its being "rebuilt," forward and back nav should function where present.
There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
