Thread:Project:Support desk/No beta features appearing after installed Beta Features extension

Currently using MediaWiki 1.23.8, PHP 5.4.38 (cgi-fcgi), MySQL 5.6.23-log and trying to get the visual editor working. Followed the wiki pages to install the Beta Features extension (link). Feature shows installed under Special:Version in Installed Extensions. I can go to Preferences -> Beta Features, but there are no features listed, just the "Automatically enable all new beta features" option.

Is there something additional that is needed to make the features appear?
