 * All of my users, authors, editors, and admin are all getting an invalid username
   when trying to login to each blog. I just upgraded to 2.7.1 and updated Akismet
   plugin and it started doing this. The site is:
 * fansidedblogs.net and I have the domain mapping plugin setup for about 80 other
   sites on this MU install. All of them no one can’t access. Please help with any
   suggestions. Thanks
 * Zach
