In your LocalSettings.php, look to see if $wgServer is set to something. (if you change the path, you would also have to potentially look at $wgArticlePath and $wgScriptPath, but it appears from your message you only changed the server). Note if $wgServer isn't set, it means its auto-detected (and appearently auto-detected incorrectly), setting it explicitly shold fix your issue.
