Некоторые ошибки сайта

[Smiler 0]

Добрый день.. недавно смотрел список ошибок на сайте. .не могу понять от чего они происходят.. Из-за того, что пользователь попадает на несуществующую страницу?

1. как быть в этом случае?

2. Из-за этих ошибок нагрузка на базу какая нибудь идет?

3. спасет ли в таких случаях nginx

Заранее спасибо!

Вообще на работу магазина никак влиять эти ошибки не должны.

Просто пишет, что нет файла 404.shtml в папке public_html.
