Hi Shah,
Sorry to hear you are experiencing difficulties.
With (Event Rocket-powered) RSVP facilities enabled as well as some tickets for WooCommerce Tickets, I see both ticket forms as expected.
While we can’t help directly with Event Rocket on this forum, I wonder if you could confirm whether deactivating Event Rocket makes any difference (to the display of the WooCommerce Tickets form)? If not, could you reply and let me know how your tickets are configured – what are the start and end sales dates and what is the stock level, for instance?
Last but not least, could you provide your System Information by way of private reply?
Thanks!
