I am looking for a plug-in to screen the applicants for a course. 

It goes like this:
- People either have an account on the site or should self-register
- The users then self-enroll to the future course where only selected content is visible.
- The they need to enter the plug-in to express their interest.
- After a deadline the administration chooses who'll attend the course and who will not.
- The chosen just remain in the course. The rejected will be unenrolled. The self-enrollment is now closed.
- The rejected users are still visible to the administration. If vacancies appear at the the minute the administration will send invitations to some, with a new deadline.
- Once the second deadline is over, the class is full.

I checked the plug-in database and thought Booking https://moodle.org/plugins/mod_booking is the right one. But it seems to be a sophisticated application. The procedure will be handed over to the administration. ;)

Am I in the right path? Is there any documentation on how to achieve this? Or do I need a different plug-in or plug-ins?

Glad that you could SOLVE the problem. It must have been something with the Academi theme.

But I don't think this statement is right:

But in moodle 4.1 the theme boost version is 2022111800, which is lower than required. I think this theme is not compatible with moodle 4.1 although it appears as such in moodle repositories.

I checked with the latest 4.1 LTS, that is 4.1.14. theme/boost/version.php has this:

$plugin->version   = 2022112800;
$plugin->requires  = 2022111800;
$plugin->component = 'theme_boost';

So the Boost theme has nothing to do with this.
