 * Everytime I try and save anything within wordpress, I get this error.
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/content/71/7784571/html/wp-content/plugins/simple-sidebar-navigation/
   settings/settings.php:175) in /home/content/71/7784571/html/wp-includes/pluggable.
   php on line 934
 * This error goes away when I deactivate the plugin, however, it is a brilliant
   plugin and I can’t live without it.
 * This is obviously something that is going to trouble the less tech savvy users.

 * It sounds like there is a white-space after a PHP closing tag in that file. Open
   the settings.php file for edit and scroll to the bottom of the code. If there
   is an extra empty line after the PHP closing tag – ?> – remove it and save the
   file. That should fix the issue. Let me know that goes. Thanks!
