Conflict with plugin Tabify Edit Screen

I activated your plugin and I an not getting this error when I attempt to access Tabify Edit Screen.

Fatal error: Cannot redeclare eyesonly_meta_box_cb() (previously declared in /wp-content/plugins/eyes-only-user-access-shortcode/includes/sseo-shortcode-generator.php:117) in /wp-content/plugins/eyes-only-user-access-shortcode/includes/sseo-shortcode-generator.php on line 18

The notice goes way if I disable your plugin or Tabify.
