Thread:Project:Support desk/How to hide HTTPS padlock icon

When I create a link to an HTTPS site, MediaWiki puts a tiny padlock icon next to the linked text. Is there a way to disable this padlock icon feature so HTTP and HTTPS links look the same?

I'm using MediaWiki Ver 1.18.1 PHP 5.3.29 MySQL 5.5.32-31.0-log
