Css problem

Hi All,
I’m italian and i don’t speak english very well, i’ve a problem with freepbx 2.10 installed on a Centos 6.2 server.

If I access to freepbx from another pc I see the freepbx gui without css and i’m not be able to use it.

If I access to freepbx from the server all working fine.

On the client pc i found this line in the css linked fron the page:
���E�t���(7_�E��[email protected]�@���o��P�e�:����P�����HTTP/1.1 200 OK

Those line doesn’t appears in the css from the server.

I need your help

Thanks very much
