Compatible avec page builder de DIVI ?

Hi,
i am afraid i am not really planning any special integration for the Divi theme, although what might work for you is adding the code below in the (child) theme functions.php file

add_action( "init", function() {
  remove_filter( "the_content", "adverts_the_content", 999 );
}, 1000 );
add_shortcode( "advert_single", function( $args ) {
    ob_start();
    if( isset( $args["post_id"] ) ) {
        $post_id = $args["post_id"];
    } else {
        $post_id = get_the_ID();
    }
        
    $post_content = get_post( $post_id )->post_content;
    $post_content = wp_kses($post_content, wp_kses_allowed_html( 'post' ) );
    $post_content = apply_filters( "adverts_the_content", $post_content );
        
    include apply_filters( "adverts_template_load", ADVERTS_PATH . 'templates/single.php' );
    $content = ob_get_clean();

    return $content;
});

Then when creating a template for Ad details pages (that is a page like https://demo.wpadverts.com/lite/advert/rayman-legends/) you should be able to use a [advert_single] shortcode which will render the Ad details.
