Here’s a fix for this issue that does not involve modifying the plugin. Add the following to functions.php in your theme or child theme:

if (! function_exists( 'rvy_get_post_meta' ) ):
function rvy_get_post_meta( $post_id, $key = '', $single = false ) {
    return get_post_meta( $post_id, $key, $single );
}
endif;
