Can't access script case after changing my apache configuration files

Hi,
I deployed my scriptcase project and tested it from localhost and it worked perfectly, then I tested the project from another machine and i got forbidden access. So i changed apache config to require all granted and then other machines could access it.

But now when i go to http://127.0.0.1:8091/scriptcase/devel/iface/login.php I get the error: Firefox can’t establish a connection to the server at 127.0.0.1:8091. I also tried it with chrome and i can’t connect.

I’m not sure where is the problem from. Would it get fixed if i reinstall wampserver? or reinstall scriptcase?

iwant download php idont can
