 * I am getting a strange header warning:
 * > Warning: Cannot modify header information – headers already sent by (output
   > started at /nfs/c06/h02/mnt/88696/domains/dw-wp.com/html/wp-content/themes/

   > includes/pluggable.php on line 868
 * I’ve followed the FAQ on here, I’ve gone through my functions file. I have deactivated
   my plugins, and re-uploaded my themes.
 * I am still getting this randomly on the wp-admin side.
 * Anyone out there have a similar incident and be willing to share what you did?
 * Thanks
 * Nadine.

 * Hi,
 * It is usually due to spaces, new lines, or other garbage at opening/closing PHP
   file <?php tag or after a closing ?> tag in wp-config.php. It can be other file
   too so need to check error message as it may list file name where the error occurred.
 * One can either upload error file from the backup or edit erroneous file. To edit
   the file one need to check below mentioned points:
 * 1. Download the file mentioned in the error message.
 * 2. Open that file in a plain text editor
 * 3. Check that the very first characters are <?php
 * 4. Check that the very last characters are ?>
 * 5. Place the cursor between the ? and >
 * 6. Now press the DELETE key on your computer and keep that key pressed for at
   least 15 seconds.
 * 7. Now type > and
 * 8. Save without pressing any other key at all.
 * That’s it!
 * Thanks,
 * Shane G.

 * Ok, I did that, but I’m still getting the same error. Any other suggestions?

 * Please test the following, open up functions.php, remove all the code minus the
   opening PHP tags, ie. `<?php`, and paste it in a txt doc if you need it, so you
   can copy it back later.
 * Save, and test your site.
 * Alternatively, rename it, create a new empty one, and test the site.

 * Works as an empty file, no errors.
 * Slowly adding functions back in to see where the issue is.
 * Thank you.
