The '''Template:1''' is currently a warning to its users. The use of Template:1 is often a typo where template parameter 1 (<nowiki>{{{1}}}</nowiki> with triple braces) was meant but, only double braces were used invoking <nowiki>"{{1}}"</nowiki> as Template:1.
However, the most problems have been caused by omitting the first brace "{" of a parameter and getting <nowiki>"{{1}}}"</nowiki>, as invoking Template:1 +"}" rather than parameter 1. This can be an insidious problem, especially when the transclusion of Template:1 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:1 now issues a warning to the user:
::* '''''Unexpected use of template <nowiki>{{1}}</nowiki>''' - see [[Template:1]] for details.''
With that warning, the prior invisible access to Template:1 can now be understood to be a formerly unseen problem coded within a page.
:''Note'': this will also pick up several variations such as <nowiki>{{1|}} for {{{1|}}} and {{{1}}</nowiki>.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:1 when trying to use parameter 1, but used only double-braces, <nowiki>{{1}}</nowiki> instead of triple-braces.
