Comment (by hellik):

 Replying to [comment:2 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.
