 * This may be coincidental, but ever since I upgraded to 4.1 I’ve been getting 
   periodic errors that prevent me from accessing my WordPress admin screen. Here
   is one such example:
 * Both my wife (melaniejackson.com) and I (fitnessBytes.net) periodically get the
   following error accessing both her WordPress wp-admin and my own. Both websites
   use the same theme (Genesis) and plugins.
 *  Bad Request
 *  Your browser sent a request that this server could not understand.
    Size of 
   a request header field exceeds server limit. Cookie /n
 * I then clear my cookies and I’m good for a while longer. I generally get this
   error twice a day and never received it before the 4.1 upgrade.
 * Other common errors I receive reject image uploads with HTTP errors.
 * I’ve searched the net but find that no one else is experiencing these problems.
 * Any help would be much appreciated.
 * Thanks

 * Try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)(
   no Dashboard access required). If that resolves the issue, reactivate each one
   individually until you find the cause.
 * If that does not resolve the issue, access your server via [FTP or SFTP](https://codex.wordpress.org/FTP_Clients),
   navigate to `/wp-content/themes/` and rename the directory of your currently 
   active theme. This will force the default theme to activate and hopefully rule-
   out a theme-specific issue (theme functions can interfere like plugins).
