Chia sẻ web không được kích hoạt trong MAC OSX10.7.4

Tôi đã thử bật tính năng Chia sẻ web trong MAC OSX 10.7.4, nhưng sau khi nhấp để kiểm tra, hãy tự bỏ chọn. Tôi biết có một câu hỏi tương tự cho nó, đó là Chia sẻ trên web (Apache) sẽ không được bật trong Lion .

Đây là nhật ký sự cố mà tôi nhận được trong tệp "/ var / log / apache2 / error_log":

Tôi đã cố gắng nhìn vào nó nhưng không thể có được lý do chính xác.
