# Admin login loop

 * I had been using the DUO Universal plugin successfully on our website for a few
   months with no problems, but sometime in the last few weeks it stopped working.
   Now when we log in to WordPress and then authenticate with DUO, we are not able
   to access the admin panel. Instead, we are redirected back to the WordPress login
   form. We can log in again and re-authenticate with DUO, but the same thing happens
   again, in a loop.
 * I’ve tried disabling all other plugins besides DUO, but we still get the same
   behavior. The only solution is to disable the DUO plugin, which is obviously 
   not our preference. **With the DUO plugin disabled we are able to log in without
   an issue.**
 * No technical changes have been made to the website since it was last working.
   I am not seeing any pertinent errors in the PHP error log, and the only logs 
   in the console appear to be informational; there are no warnings or errors related
   to DUO.
