[Mediawiki-l] Migrating Wikis

[Richard Kurz]

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.
