title: WordPress login Not Acceptable
body: <p>to start...
  I have this error message when I try to login (don't even need to fill anything and click log in, this message appears too)</p>
  
  <pre><code> Not Acceptable
  
  An appropriate representation of the requested resource /wp-login.php could not be found on this server.
  
  Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. 
  </code></pre>
  
  <p>but then the page title says 406 Not Acceptable</p>
  
  <p>I have search around and saw some posts with .htaccess and I tried but still can't get it to work.</p>
  
  <p>Ok how this happened was, I was using Chrome and logged in for hours doing my stuffs. But then because of some reason I had to reset password for the original user named admin. So then after password was reset, I tried to login with firefox and the error appeared. At first I thought there's something with admin user so, since my chrome is still logged in (my own login is roled as administrator) I used my login to delete the admin user and created a new one with other name.
  Then I tried with firefox again with the new name I created I saw the error. Then I used my own login and same error happened. Then I realized, I don't have to do anything and just by pressing login this error happens.</p>
  
  <p>Now I am afraid to close my Chrome because it's still logged in and working there.</p>
  
  <p>P.S. I tired adding this too</p>
  
  <pre><code>&lt;IfModule mod_security.c&gt;
     # Turn off mod_security filtering.
     SecFilterEngine Off
  
     # The below probably isn't needed, but better safe than sorry.
     SecFilterScanPOST Off
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>in <code>.htaccess</code> where is located same location as wp-config and others</p>
  
  <p>P.S this is getting more confusing for me.  I tried using my phone and co-worker's phone to login into wp-admin and works like nothing ever happened.  But I used both of our desktop to login into wp-admin and both desktop tried firefox and chrome.  Same errors.</p>
