 * Hi there,
 * Just an FYI that MemberPress and WP Session Manager have a slight conflict. Our
   logs are full of the following warning;
 * [29-May-2017 00:27:49 UTC] PHP Warning: Cannot modify header information – headers
   already sent by (output started at /vagrant/wp-content/plugins/memberpress/app/
   controllers/MeprAppCtrl.php:908) in /vagrant/wp-content/plugins/wp-session-manager/
   includes/class-wp-session.php on line 128
 * I’ll let the developers of the other plugin know as well.
 * Cheers,
    Phil
