Thanks for the response. However, "Try setting the ServerName directive in httpd.conf" - I cannot find the httpd.conf file Also, "$wgServer variable in LocalSettings.php like this: $wgServer = 'http://myrealhostname.myrealdomain.com'" I cannot find this variable as well. Any suggestions?

It's annoyingly common for Apache to think it's running on "localhost" or a non-fully-qualified or internal-only hostname, and this invalid hostname gets handed to PHP and we use it when constructing redirect headers. Try setting the ServerName directive in httpd.conf, or override the $wgServer variable in LocalSettings.php like this: $wgServer = 'http://myrealhostname.myrealdomain.com'; (You need the http:// or https:// on the front here.) You might have similar problems if running on a non-standard port over some kind of port redirect mechanism or proxy such that the web server doesn't know what port number the clients use. If this doesn't clear it up, you might use the 'Live HTTP Headers' extension for Mozilla or Firefox, or a network traffic sniffer capable of interpreting HTTP (like Ethereal) to double-check exactly what's being sent between the browser and the server. I find the Live HTTP Headers extension to be an invaluable web debugging tool, and it's very easy to switch on when you need it: http://livehttpheaders.mozdev.org/ -- brion vibber (brion @ pobox.com)
