Problem I'm having:

Warning: Cannot modify header information - headers already sent by (output started at /nfs/c06/h02/mnt/157520/domains/website/html/rpow/wp-config.php:1) in /nfs/c06/h02/mnt/157520/domains/website/html/rpow/wp-includes/pluggable.php on line 1207

I've tried to use FileZilla to find blank/invisible spaces and such in index.php and wp-config.php, I've tried to reinstall WordPress and replace index.php and wp-config.php with default files, I tried to resave files as UTF-8, but none of that worked. Is there anything that I haven't tried that might work? I can post both of my PHP files if necessary (I don't know where to upload them though).

  • Here you can read a very good discussion on the topic. Since this is the wp-config file, it could be that you have some whitespace before the <?php tag. – denis.stoyanov Sep 23 '15 at 17:14

Have you tried turning off errors / warnings on your Server? Maybe no per WP_DEBUG, but rather some setting on your Servers admin interface.

Many times I encountered this error, it was caused by a Warning of some plugin.
