Hi there,
Thanks for reaching out to us.
At the moment we are experiencing high traffic in our forums. Our response time might be a bit longer than usual, our apologies for this.
One of our support members will help you out as soon as possible.
Thank you for your patience!
A good starting point would be our Themer’s Guide: https://theeventscalendar.com/knowledgebase/themers-guide/
You will likely need to create an override for this file:
wp-content/plugins/the-events-calendar/src/views/list/single-event.php
And place an override here:
wp-content/themes/[your-theme]/tribe-events/list/single-event.php
Cheers,
Andras
