Hi there @graphisterie02,
That’s definitely possible. Please do familiarize yourself with our Themer’s Guide in the first instance, which covers some of the basics in relation to customizing The Events Calendar 🙂
There are a few ways to tackle this, but a fairly easy approach would be to use a template override. In this case, that would mean locating the following template file:
the-events-calendar/src/views/single-event.php
Then copying it to your theme:
YOUR-THEME/tribe-events/single-event.php
Within that copy, you will see some code like this:
if ( ! defined( 'ABSPATH' ) ) {
die( '-1' );
}
Right after that, you could add something like:
if ( ! is_user_logged_in() ) {
echo 'Content available only when logged in';
return;
}
Perhaps that would work for you?
