[PHP] pobierz, plaintext 

Jednak dostaje komunikat:

td_shortcode (parse error in /modules/td_shortcode/td_shortcode.php)
td_shortcode (class missing in /modules/td_shortcode/td_shortcode.php)

niestety bez podanych linii błędów, mógłby ktoś rzucić okiem na to?

Dokumentacja prestashop:

Masz na myśli podkreślnik?

zmieniłem na

[PHP] pobierz, plaintext 
$this->name = 'tdshortcode';
[PHP] pobierz, plaintext 

oraz nazwę pliku i folderu, błąd nadal identyczny czyli:

[PHP] pobierz, plaintext 
tdshortcode (parse error in /modules/tdshortcode/tdshortcode.php)
tdshortcode (class missing in /modules/tdshortcode/tdshortcode.php)
[PHP] pobierz, plaintext 

Podbijam, czy ktoś może mi wskazać czy i gdzie jest błąd?

Nazwa pliku, nazwa klasy oraz atrybut Name powinny być identyczne.

Dzięki.
