Hey @ruddygood,
Thanks for reaching out! I think that those methods mentioned in that thread actually WILL work, but only when your software is up-to-date.
Your version of The Events Calendar is very out of date, and your version of WooCommerce Tickets is super out of date! Your first order of business should be updating immediately. Here are the most recent versions of these plugins and where to download them so that you can update:
• The Events Calendar – 3.12.3 → https://wordpress.org/plugins/the-events-calendar/
• WooCommerce Tickets – 3.12 → https://theeventscalendar.com/my-account/downloads/
Your version of WooCommerce is out of date too. You should update to its most recent version, 2.4.7, which you can do here → https://wordpress.org/plugins/woocommerce/
Once everything is updated, try the script Brian recommended in that support thread, which is available here → https://gist.github.com/jesseeproductions/7ec5827ffa34a3995dc9
Just copy and paste that script into your theme’s functions.php file.
I hope this all helps!
