Now things are /mostly/ sorted. The "www" ain't appearing no more (somehow cpanel--my new nemesis--had the virtual host listed in two places).
One issue is that the URLs on the pages still have "index.php" in them a'la:
This isn't the end of the world, since it still works without it:
I just can't get mediawiki to drop it (ok, i've looked at it for precious few minutes...).
The relevent bits of LocalSettings.php say:
$wgScriptPath = "/index.php";
$wgScript = "$wgScriptPath";
$wgRedirectScript = "/redirect.php";
$wgArticlePath = "/$1";
The wgArticlePath, I'd think, would drop out the index.php.
Anyhoo, if there is someone out there that knows mediawiki, can you hit me with a cluebat?
