Usage

Template:{{{1}}} is currently a warning to its users. The use of Template:{{{1}}} is often a typo where template parameter {{{1}}} (as {{{{{{1}}}}}} with triple braces) was meant, but only double braces were used, invoking {{{{{1}}}}} as Template:{{{1}}}. In addition to displaying 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 [[Special:WhatLinksHere/Template:{{{1}}}|what-links-here]] to see if anyone has accidentally invoked Template:{{{1}}}.
