I am using a function in functions.php to get posts and pages displayed on the homepage.

     add_filter( 'pre_get_posts', 'my_get_posts' );
     function my_get_posts( $query ) {
     if ( is_home()) {
     $query->set( 'post_type', array( 'post', 'page') );
     $query = apply_filters( 'the_content', $query);
     return $query;
     }
     }

I noticed that by doing this, the page does not render shortcodes and ignores the fact that a page template is assigned to the page. So I tried using passing the return $query through a filter like so

    $query = apply_filters( 'the_content', $query);

but then I get this error Object of class WP_Query could not be converted to string

I don't know any way around it. Do you?
