Unexpected use of template {{3}} – see Template:3 for details.
Template documentationUsage
ಬದಲಾಯಿಸಿTemplates {{1}}, {{2}}, ... {{9}} warn to their users, indicating a typo in their template edit. If {{3}} is called, you probably meant the parameter 3 (as {{{3}}} with triple braces), but in fact only double braces were used, invoking {{3}}. In addition to a warning, it also adds pages to ವರ್ಗ:Templates with incorrect parameter syntax.
However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{3}}}, as invoking Template:3 +"}" rather than parameter 3. This can be an insidious problem, especially when the transclusion of Template:3 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:3 now issues a warning to the user.
With that warning, the prior invisible access to Template:3 can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{3|}} for {{{3|}}} and {{{3}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:3.
