After upgrading Apache to 2.2.23 there is a problem
I (perhaps foolishly) upgraded Apache from 2.2.22 to 2.2.23 on OS X Mountain Lion Server. Following the upgrade, remote clients on the LAN cannot access the Web server's default.html.en web page. The DNS entries still look okay on OS X Mountain Lion Server.
Any ideas as to what might have got broken/overwritten by Apache by doing the upgrade that I need to fix or could something be blocking things?
Also, while probably not related, when, directly from the (updated) web server machine, I access 127.0.0.1 from within the web browser I can see the start up web page for Apache on OS X Server (so Apache is running, just can't be accessed remotely). However, when I try to access the same web page, again directly from the local web server machine, but this time using localhost instead of the IP address in the URL then the web page doesn't appear.
The hosts file on the web server has the following entries:
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
