Hi Michael,
Thanks for getting in touch with us! I can help you here 🙂
First install and activate the following plugins: The Events Calendar, Event Tickets (rsvp tickets), Event Tickets Plus + an e-commerce plugin (WooCommerce, Easy Digital Downloads, WP-Ecommerce or Shopp) if you are planning to sell tickets in the site.
Once all the plugins are installed, just go to the ‘Add New Event’ screen an scroll down, below all event related fields you should see the tickets meta box to create tickets.
Be sure to check out this article covering the basic setup: New User Primer: Event Tickets & Event Tickets Plus.
Please let me know if you see the tickets options now,
Best,
Nico
