 * Plugin Name: FV Player - MemberPress Courses fix
 * Version:     0.2
 * Description: Since memberpress-courses/app/views/classroom/courses_footer.php doesn't contain wp_footer hook we have to provide an alternative way of loading FV Player scripts. Here's another description of the issue: https://blog.calendarscripts.info/watu-watupro-and-memberpress-temporary-solution-to-an-issue/
