Usage

Templates {{1}}, {{2}}, ... {{9}} warn to their users, indicating a typo in their template edit. If {{1}} is called, you probably meant the parameter 1 (as {{{1}}} with triple braces), but in fact only double braces were used, invoking {{1}}. In addition to a warning, it also adds pages to Category:Templates with incorrect parameter syntax.

However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{1}}}, 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.

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 {{1|}} for {{{1|}}} and {{{1}}.

Periodically, people check what-links-here to see if anyone has accidentally invoked Template:1.
