Clubs Plugin flush fix

gistfile1.php

function clubs_rewrite_flush() {
	// First, we "add" the custom post type via the above written function.
	// Note: "add" is written with quotes, as CPTs don't get added to the DB,
	// They are only referenced in the post_type column with a post entry, 
	// when you add a post of this CPT.

	// Both the custom post type and the custom taxonomy need to be called in this instance
	create_club_post_type();
	create_clubs_taxonomies();

	// You should *NEVER EVER* do this on every page load!!
	flush_rewrite_rules();
