Welcome back to the forums, Edwin!
There are a few ways to hide/remove the “Details” section from your single event pages. The first is through CSS. Try adding the following code to your style.css file:
.tribe-events-meta-group tribe-events-meta-group-details {
display: none;
}
Your next option would be to overwrite the existing code through a template override (as you mentioned in your original post). The file you’ll need to look into is the-events-calendar/src/views/modules/meta/details.php.
Hopefully this helps point you in the right direction! Let me know if there is anything else I can help with and have a great rest of your week 🙂
