I want users to be able to take the quiz multiple times, but I don't want them to do it by clicking the try again button after the results are shown (I have a menu bar link which they can click to try again).

Please can you tell me which php file I need to edit to remove this button completely? Thanks.

EDIT:

I got it eventually. The file is: components/com_communityquiz/layouts/bootstrap5/results/actions.php

and you need to use css to hide the button. here is the new line:

<a href="<?php echo Route::_( CommunityQuizHelperRoute::getQuizRoute( $item->id, $item->catid, $item->language, $item->course_id ) ) ?>" class="btn btn-primary" style="display: none;">
