 * Hi support. I need your help please. I cannot get into my backend. I’m getting
   this error:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/content/03/13163103/html/Fox/wp-includes/meta.php:1) in /home/content/
   03/13163103/html/Fox/wp-includes/pluggable.php on line 1228
 * Website is [http://www.foxemerson.com](http://www.foxemerson.com) and backend
   is [http://www.foxemerson.com/wp-admin](http://www.foxemerson.com/wp-admin) which
   is where i get the error.
 * I am not able to understand this and need some help. I haven’t installed any 
   new plugins, it just happened after updates automatically installed. Can you 
   please help me urgently? I don’t know what to do. I can provide you logins.
 * Thanks

 * Can you send me screen shot of your wp-includes/meta.php.
    This file can’t be
   access via admin menu and can only be accessed through FTP.

 * You can change it yourself too.Try the codes below:
 * 1.The warning refers to output in line 1 in meta.php,could be due to leading 
   whitespace, text or HTML before the opening <?php token in meta.php
    Make sure
   <?php has nothing before it, even whitespace too.
 * 2.Make sure there is no gap between ?> and <?php throughout meta.php
    You can
   do it by FIND AND REPLACE in any editor.
 * 3.Try adding ob_start(); function at the very top of your meta.php and ob_end_flush();
   at the very end of the document but between <?php and ?> for eg.
    <?php ob_start();
 * ob_end_flush();
    ?>
 * I hope it will help resolve your issue.

 * Hi. That didn’t work. I hired someone on Fiverr to help find the problem but 
   they’ve just given up 🙁
