config nginx

[AdamWlkp33]

Zmieniłem serwer www z apacha na nginx i mam problem z poprawną konfiguracją. Obecnie całość działa dobrze z wyjątkiem strony podsumowania transakcji gdzie łapie 500 z modułu. W error logu brak błedów, lecą tylko mało znaczące noticy z php.

Proszę o weryfikacje i sugestie co może być przyczyną.
