No registration form

Hi,
I cannot put on a login or registration form for my courses. I also would like to remove the option “buy now” on my course page. I want my clients to book via “Boka nu” and then I will manually activate them, send them a link to the course with a login option. I’ve tried to enable “anyone can register” but it still doesn’t work.

I also want to remove or rename “Curriculum” since the name in Swedish is very elementary schoolish. I tried to add the code below, but it doesn’t work.

Please, please do you have a solution for this?

Wish you the best,
Charlotte

function theme_prefix_lp_course_tab_remove( $tabs ) {
unset( $tabs[‘curriculum’] );
return $tabs;
}
