I'm getting an error (as follows) in define_pages_editor when trying to save.

Warning: Cannot modify header information - headers already sent by (output started at /home/content/f/r/a/frankandmonkey/html/admin/define_pages_editor.php:121) in /home/content/f/r/a/frankandmonkey/html/admin/includes/functions/general.php on line 67

There aren't any spaces at the bottom of the file (and it's erroring out before it ever gets there anyhow.) PHP file is as follows, please help!
