Hello Hector Cabrera !

Thank you very much for your help ! I had to make some few changes to the code you gave me, so I post my final code here.
In particular, I had to add a ‘foreach’ concerning the categories, as the code was only returning the word “Array”.. And I added a substr() for my title length 🙂

function my_custom_single_popular_post( $post_html, $p, $instance ){
    $pp_categories = get_the_category($p->id);
    if($pp_categories){
        foreach ($pp_categories as $pp_category){
            $pp_categoryout = '<a href="'.get_category_link( $pp_category->term_id ).'" class="cat-id-' . $pp_category->term_id . '" title="' . esc_attr( sprintf( __( "Voir tous les articles dans %s" ), $pp_category->name ) ) . '">'.$pp_category->cat_name.'</a>';
        }
    }
    $output = '
        <li class="popular-postid">'
            . get_the_post_thumbnail( $p->id, 'wpp_thumb' ) . '<br />
            <span class="pp-cat">' . trim($pp_categoryout) .'</span><br />
            <a href="'.get_permalink($p->id).'" title="'. esc_attr($p->title) .'" class="wpp-post-title" >'. substr($p->title, 0, 25).' (...)</a><br />
            <span class="pp-date">' . date( 'd M Y', strtotime( $p->date ) ) . '</span>
        </li>';

    return $output;
}

add_filter( 'wpp_post', 'my_custom_single_popular_post', 10, 3 );

It’s all good now ! Again, thank you very much ! 🙂
