I just installed a new xampp package (5.6.23) for windows to upgrade a previous package (5.4.27). I kept the old installation, and can run either package from their respective control panels. I can reach the old install from localhost and any other computer on my house network with no problem. However, I can only reach the new install using localhost. Any other computer times out trying to reach a valid page. I have been over the httpd.conf file for the new package many times, comparing to the old installation. Both use the directive "Listen 80". Everything else is the same as well. Both show they are listening on port 80 on the control panel. Same browser, same computers, same server, same firewall, same web pages... Can anyone help?
