Since MediaWiki 1.32, MediaWiki no longer has a "JavaScript-powered" wikitext toolbar built in. The old "bulletin board style toolbar", known as "the 2006 wikitext editor", has been removed, and instead sysadmins will be required to choose one (or more) of the several extensions available for this purpose if they need the functionality. The MediaWiki "tarball" releases have included the replacement extension for this, the $1 extension aka "the 2010 wikitext editor", for many years now. Be sure this extension has been installed.
