Thread:Project:Support desk/formatting issue, related to $wgServer?

MediaWiki 1.22.3 PHP 5.4.34 MySQL 5.5.40-36.1

I am having a problem with the formatting of my wiki when accessed on certain computers. When I access my page on most computers it looks fine, but when I pull it up on the computers at the hospital where I work, it has no formatting and no images. The problem is the same in internet explorer and chrome. Other wikis, including wikipedia and mediawiki, work normally on these computers.

I believe the problem is related to $wgServer, based on the help topic "The wiki appears without styles applied and images are missing" in "Manual:Errors and symptoms." From reading this, though, I couldn't figure out how to fix the problem. Would using short URLs on my wiki fix the problem?
