Tam taki problem, który nie wiem jak rozgryźć. Mam stronkę, która sobie działa, ale kiedy korzystam z narzędzia do generowania sitemapy dla google (http://www.auditmypc.com/xml-sitemap.asp) pojawiają się problemy:
- Narzędzie nie może stworzyć sitemapy
- Po uruchomieniu narzędzia, na stronie pojawiają się błędy:

Znowu odświeżę to znowu dostanę podobny błąd. Po ok. minucie, czy dwóch, wszystko wraca do normy, a strona działa. Gdzie mogłem zrobić błąd?
