Category:Pages using duplicate arguments in template calls

Template:Wikipedia category Template:Backlog Script error: No such module "Message box". This category contains pages with template calls that pass the same argument (parameter value) more than once, such as {{foo|bar=1|bar=2}} and {{foo|bar|1=baz}}. When the same parameter is given a value more than once in a template, only the final value of that parameter is used to display the template.

• When checking Template:Keypress, any double parameter (and its template) will be listed in top as an error.
