Hi Matt, thanks for getting in touch! Sorry you’re hitting some trouble but hopefully we can tackle this together. 🙂
I was able to use the snippet from the tutorial on my end. Granted, I’m unfamiliar with the Snippets plugin, but I wonder if it’s not adding it correctly for you. Are you able to edit functions.php without the plugin? You can do this directly in WordPress (Appearance > Editor, select “Theme Functions” from the right column).
From there, you should be able to paste this snippet direct at the bottom of functions.php:
remove_action( 'tribe_events_single_event_after_the_meta', array( TribeWooTickets::get_instance(), 'front_end_tickets_form'), 5 );
add_action( 'tribe_events_single_event_after_the_content', array( TribeWooTickets::get_instance(), 'front_end_tickets_form'), 5 );
Will that work for you? Please let me know. 🙂
Geoff
