apache - 阿帕奇问题

Question

我正在尝试在 Wampserver 中启动 apache。

该图标保持橙色，即使：

I have terminated skype, 
port forwarded port 80, 
the service is installed, 
port 80 is open and is not being used by any program or service 
and i've set the ip for listening to: 0.0.0.0:80 

可能是什么问题？

谢谢！PS它以前有效，但现在，它没有。从那以后我没有做任何改变。
