Recurring error: Cannot modify header information (2 posts)

    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!
