Comment (by Jeff McKenna):

 I didn't make any recent changes, not sure why this occurred.

 It seems that this is a common issue though, and one of the solutions is
 to modify php.ini with the following change:

 {{{
 session.referer_check = off
 }}}

 I restarted Apache and now I can login.

 It is a quick-n-dirty solution, maybe the original error is due to a
 session file trying to write to a write-protected folder?  (not sure why
 the permissions would change suddenly though).

 Or maybe someone did an update on that VM and PHP was upgraded?  Not sure.

 Let me know if this change is enough.
