Instructions for setting up a favicon for MediaWiki are here, but I can't get them to work.
My DreamHost wiki is at ghanawiki.info. I've created a favicon.ico file and uploaded it to my DreamHost account under the ghanawiki.info/ directory (that's the webroot). I've also added the following entry to LocalSettings.php:
$wgFavicon = "/favicon.ico";
However, none of these changes causes the favicon to appear in the address bar. Also, if I visit http://ghanawiki.info/favicon.ico, I get a MediaWiki page saying "There is currently no text in this page".
Does anyone know what I'm doing wrong? Thanks.
