[sửa mã nguồn]Templates {{1}}, {{2}}, {{3}} etc warn readers/editors that a typo exists in the page they are reading/editing. If {{4}} is called, you probably meant the parameter 4 (as {{{4}}} with triple braces), but in fact only double braces were used, invoking {{4}}. 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 {{4}}}, as invoking Template:4 +"}" rather than parameter 4. This can be an insidious problem, especially when the transclusion of Template:4 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:4 now issues a warning to the user.
With that warning, the prior invisible access to Template:4 can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{4|}} for {{{4|}}} and {{{4}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:4.
