Category:Articles using invalid arguments in template calls

__HIDDENCAT__ The following pages have template misuse warnings. Unlike full script errors, warnings are displayed only to editors so as to not disrupt the reader experience. Oftentimes, validation errors are not so critical that readers need to know about them.

Warning messages are displayed above page previews, unless the preference  is enabled. If that's the case, the warnings can also be viewed in the Lua logs at the very bottom of the preview page beneath the editing area, under "parser profiling data."

Unfortunately warning messages cannot be viewed when using VisualEditor, even in source mode. To switch to the regular source editor, go to Special:Preferences,  tab, and from the   dropdown select.
