Custom section in account page

Hi! Thanks for the awesome plugin.

Can you help me a bit please? I followed that tutorial:

https://wedevs.com/docs/wp-user-frontend-pro/developer-docs/add-a-new-tab-on-my-account-page/

Added that code to functions.php:

function wpuf_my_page( $sections ) {
    $sections = array_merge( $sections, array( array( 'slug' => 'addmypost', 'label' => 'Добавить пост' ) ) );

    return $sections;
}

add_action( 'wpuf_account_content_my-page', 'wpuf_addmypost', 10, 2 );

function wpuf_addmypost( $sections, $current_section ) {
    wpuf_load_template(
        "dashboard/addpost.php",
        array( 'sections' => $sections, 'current_section' => $current_section )
    );
}

Then added that code to addpost.php:

<?php global $current_user; 

echo do_shortcode('[wpuf_form id="1048"]');

?>

The 4th menu item appeared, however shortcode doesn’t load. Where exactly should I upload addpost.php?

• /wp-content/themes/theme/wp-user-frontend/templates/dashboard/
• /wp-content/themes/theme/
• /wp-content/themes/theme/wp-user-frontend/

Or is there anything else that I did wrong? Thanks!
