 * I am getting this information when I log into my site
    Warning: Cannot modify
   header information – headers already sent by (output started at /home/cordery/
   public_html/wp-config.php:1) in /home/cordery/public_html/wp-includes/pluggable.
   php on line 1178
 * I have checked all the support on this matter and it all says to remove the blank
   space at the start and end of the wp-config file as that is the one that all 
   the documentation says to look at. I have checked and double checked there is
   no spaces. Deleting everything prior to the <?php and after the ?> I am working
   in Notepad to modify the files and there is definitely no other characters I 
   can see.
 * Are there any other suggestions on how to solve this?

 * Hello bigbadbr,
 * Hope you’re well! 🙂
 * Could you post your wp-config.php or you can use pastebin.com for this then just
   link it here. Just don’t forget to replace/remove the DB credentials and SALT
   keys.
 * Also try to disable all your plugins just to make sure we don’t miss an obvious.
   🙂 You can do this via ftp client if you don’t have access to your dashboard.
 * Looking forward for your reply! 🙂
 * Best Regards,
    Calvin

 * Hi friend,
 * **Open your wp-config.php file, “Save as” UTF-8 without BOM.**
    That’s it! 🙂
 * Good days.
