Sorry for the inconvenience. Known Navigation header breakage of “Previous:” and “Next:” links, the Table Of Contents may be the solution for those.
However, unfortunately, the Table of contents may also be broken, and there may be other unforeseen breakage primarily in the handbook portion of the wiki.
Presently the 10.1 and 10.1.1 Table Of Contents are being "reconstructed" becoming incrementally fixed while the other handbook versions may have various breakage.
