Hello, on the two wikis I am an admin of it states that

ShowHide is no longer supported, but is in use on this page. You should consider switching to the MediaWiki collapsible selectors, such as class="mw-collapsible". See the Collapsing help page for more details.

The thing is, since I am not shown what templates it is referring to or if it is a MediaWiki, I can't do anything about it, properly.
