Access Xampp outside loclamachine

[Guguy]

Hi, here's my noob problem:

I have installed xampp on windows, as well Wordpress, modx and moodle platforms.
They are well configured as they run on localhost.
The problem: when i try to access from other computer on same network by xampp IP Adress, xampp page is right displayed, as well the myphpadmin page, but externat modules like moodle, modx or wordpress, pages are not displayed! only html code is displayed.

How to access them???

Thanks in advance!
