 * I am getting this error: Warning: Cannot modify header information – headers 
   already sent by (output started at /home/lowco25/public_html/wp-content/themes/
   LowcoTheme/functions.php:1) in /home/lowco25/public_html/wp-login.php on line

 * I looked at the troubleshooting page, before the error was in Pluggables.php 
   but after following the troubleshoot directions I now get this error.
 * This started occurring after installing bbpress enable tinymce visual tab. But
   now I cannot get in to remove the plugin. It is not active. I deleted the files
   via FTP.

 * Update: I deleted the theme and the problem went away, going to try and reupload
   a “fresh” version of the theme and see what happens.
