If you want to make Version 2.1.5 work again, just go into “inc/course” and open the lp-course-functions.php

There you have to remove lines 757 to 775. The following has to be removed:

add_action( 'template_include', 'learn_press_prepare_archive_courses' );
function learn_press_prepare_archive_courses() {
	global $wp_query;
	$query = !empty( LP()->wp_query ) ? LP()->wp_query : $wp_query;
	if ( !$query || !$query->is_main_query() ) {
		return;
	}
	if ( !empty( $query->posts ) ) {
		$ids = array();
		foreach ( $query->posts as $_post ) {
			$ids[] = $_post->ID;
			$_post = sanitize_post( $_post, 'raw' );
			wp_cache_add( $_post->ID, $_post, 'posts' );
		}
		_learn_press_get_courses_curriculum( $ids, false, false );
		_learn_press_count_users_enrolled_courses( $ids );
		//update_meta_cache( 'post', $ids );
	}
}

Same here, even with their Thimpress Themes. We have to wait for an update.
