Thread:Project:Support desk/Problems with skins and logo

I have installed Mediawiki and followed the directions to a T for adding a logo, and it still doesn't appear. here are all the ways I tried it. $wgLogo				= 'http://www.nwldev.com/wiki65/skins/common/images/logo.png'; $wgLogo				= 'common/images/logo.png'; $wgLogo				= '/common/images/logo.png'; $wgLogo				= "common/images/logo.png"; $wgLogo				= "skins/common/images/logo.png"; $wgLogo				= "../skins/common/images/logo.png";

I don't know what I'm doing wrong, but the logo won't show up.

Also on the skin, I downloaded gumaxdd skin, dropped it with the two php files into the skins folder. and tried this: $wgDefaultSkin = 'gumaxdd';

But the skin does not show up. Any help would be much appreciated.
