“Fatal error” comes up when I publish post

So I just updated this plugin but this comes up when I publish a new post:

Fatal error: Uncaught Error: Cannot use object of type WP_Taxonomy as array in /home/wp_urnhvf/vanndigital.com/wp-content/plugins/varnish-http-purge/varnish-http-purge.php:530 Stack trace: #0 /home/wp_urnhvf/vanndigital.com/wp-includes/class-wp-hook.php(298): VarnishPurger->purgePost(134207, Object(WP_Post)) #1 /home/wp_urnhvf/vanndigital.com/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters(NULL, Array) #2 /home/wp_urnhvf/vanndigital.com/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /home/wp_urnhvf/vanndigital.com/wp-includes/post.php(3472): do_action('edit_post', 134207, Object(WP_Post)) #4 /home/wp_urnhvf/vanndigital.com/wp-includes/post.php(3583): wp_insert_post(Array, false) #5 /home/wp_urnhvf/vanndigital.com/wp-admin/includes/post.php(378): wp_update_post(Array) #6 /home/wp_urnhvf/vanndigital.com/wp-admin/post.php(193): edit_post() #7 {main} thrown in /home/wp_urnhvf/vanndigital.com/wp-content/plugins/varnish-http-purge/varnish-http-purge.php on line 530
