Change the UNIVERSE_URL line to:
define("UNIVERSE_URL", "http://militaristic.org/universalunreal/");

You have the following line:
ServerURL=24.45.220.14

But your installation doesn't seem to have this server configured in your server list? From the web you need to add this server and give it a unique short name, then set "ShortServerName=" to whatever the new short name is for the new entry.

Also the ServerURL field must contain a UT port. You probably mean to have it:
ServerURL=24.45.220.14:7777

Here's an example to help you, from one of my servers. The server's IP is "208.71.112.193" and it is running on port 7777:

[UniversalUnreal111-Build1.UniversalUnreal]
UniverseID=UT-SLV
UniversePass=xxxxxxxxxxxxx
UniverseHost=www.ut-slv.com
UniverseFilePath=/universalunreal/utinterface.php
UniversePort=80
ServerURL=208.71.112.193:7777
TCPServerPort=7777
shortServerName=KOA
bDisableDuringMatchMode=False
UniverseAboutURL=http://www.ut-slv.com/universalunreal/index.php?p=about
MaxTimeout=20
ErrorLimit=10
bDebug=False
resolvedAddress=
CollectPlayerData=True
bHideHUDForGuests=False
ServerListYOffset=0
bNeverPurgeAddress=False

And my constants.php file:

define("DB_SERVER", "localhost");
define("DB_USER", "xxxxxxx");
define("DB_PASS", "xxxxxxx");
define("DB_NAME", "xxxxxxxx");

define("UNIVERSE_ID", "UT-SLV");
define("UNIVERSE_PASS", "xxxxxxxxxxxxxxx");

define("UNIVERSE_ADMIN_NAME", "MSuLL");
define("UNIVERSE_ADMIN_EMAIL", "[email protected]");

// you must correctly enter the world-viewable URL to this installation, and it *MUST END IN A FORWARD SLASH!*
define("UNIVERSE_URL", "http://www.ut-slv.com/universalunreal/");

// welcome message on the front page, change to define("PORTAL_MSG", ""); to disable
define("PORTAL_MSG", "Welcome to the UT-SLV installation of Universal Unreal! Report all bugs / concerns / suggestions to MSuLL via the Universal Unreal forum thread at:<br><a href=\"http://www.ut-slv.com/forum/viewtopic.php?f=11&t=2719\">http://www.ut-slv.com/forum/viewtopic.php?f=11&t=2719</a>");

define("LOG_PLAYER_DATA",True);

define("EMAIL_FROM_NAME", "UT-SLV Universe");
define("EMAIL_FROM_ADDR", "[email protected]");

define("SMTP_USE",False);
define("SMTP_HOST", "mail.myhost.com");
define("SMTP_PORT", 25);
define("SMTP_USERNAME","someuser");
define("STMP_PASSWORD","somepass");

define("QUERY_METHOD",0);

If you still have trouble, the UT config set bDebug=true and post the log again. Hope this helps.
