If your BuddyApp site is hosted with WP Engine then you will need some minor changes to make BuddyPress work seamlessly. This is a problem that is not related to the theme but something that has to do with WP Engine system.
1. Activate your BuddyApp Child theme if it is not already enabled.
2. Go to WP Admin > Appearance > Editor > BuddyApp Child > Functions.php and paste the below code on a new line at the end of the file.
COPY CODE
add_action( 'wp_enqueue_scripts', 'load_buddypress_js' );
function load_buddypress_js () {
if (bp_is_group() || is_page( 'activity' )) {
wp_enqueue_script('buddypress_query',plugins_url() . '/buddypress/bp-core/js/jquery-query.min.js',array("jquery"));
wp_enqueue_script('buddypress_members',plugins_url() . '/buddypress/bp-core/js/widget-members.min.js',array("jquery"));
wp_enqueue_script('buddypress_cookie',plugins_url() . '/buddypress/bp-core/js/jquery-cookie.min.js',array("jquery"));
wp_enqueue_script('buddypress_scroll', plugins_url() . '/buddypress/bp-core/js/jquery-scroll-to.min.js', array("jquery"));
wp_enqueue_script('buddypress_js',get_template_directory_uri() . '/buddypress/js/buddypress.min.js',array("jquery"));
}
}
3. Save your code and clear your caches.
