Yes, same thing has happened to me after the upgrade, where the tickets should be I am getting this error instead instead.
Warning: include() [function.include]: Failed opening ‘/home/clifdena/staging/1/wp-content/plugins/wootickets/views/wootickets/tickets.php’ for inclusion (include_path=’.:/usr/local/php53/pear’) in /home/clifdena/staging/1/wp-content/plugins/wootickets/classes/class-wootickets.php on line 423
Any help would be great!
