==Overview==
{{see|Help:Footnotes}}
References are defined within <syntaxhighlight lang="HTML" inline><ref></syntaxhighlight> tags.

==Issues and resolution==
* There is no content between the <syntaxhighlight lang="HTML" inline><ref></syntaxhighlight> tags, and the reference has no name. Either delete the two tags, or put content between them, for example: {{tag|ref|content={{var|content}}}}; or, if you're reusing a named reference that's been defined elsewhere in the article use a single tag, for example {{tag|ref|s|params=name="{{var|refname}}"}}
* There is an <code>=</code> (equals sign) in an explanatory footnote: <code><nowiki>{{efn|Explanatory footnote with = sign}}</nowiki></code>. Unnamed template parameters cannot contain an equals sign. To solve this issue, start the parameter with <code>|1=</code> like this: <code><nowiki>{{efn|1=Explanatory footnote with = sign}}</nowiki></code>
