Hi, I'm migrating the contents of my wiki from HTTPS to HTTP, all other things remaining the same. I've copied all files to the httpdocs directory on my server, and I've added a line in LocalSettings.php that says

$wgServer="http://heritage.web.lehigh.edu";

When I navigate to the HTTP address, all I get is a blank screen. What else can I change (and where should I find it?). Thanks in advance for all help.
