Good evening MichaelĀ and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about the ability to put prices on ticket not appearing on your installation.
I would love to help you with this topic.
Based on your system information, I have good reason to believe this might be caused by a simple mixed-content issue.
Could you please check in WP-Admin under Settings if both of the URLs are set to https ?
Secondly, would you mind sending me a screenshot of your Add Ticket interface ?
Hang in there,
Best regards,
Geoff B.
