Help: CS1 errors

A {{cs1}} or {{cs2}} template marked as "Empty" contains no recognizable parameter identifiers. For example, this citation is marked as "empty" even though it contains usable information:
:<code><nowiki>{{cite web |http://www.foobar.com |The Foobar News}}</nowiki></code>
The citation is "empty" because it does not contain the necessary parameter identifiers (in this case {{para|url}} and {{para|title}}) that tell {{tlx|cite web}} how to use the information that the citation contains.

A citation is also marked as "empty" when it contains only parameters that it doesn't recognize:
: <code><nowiki>{{cite book |titolo=The Bazquux Uprising |anno=2015}}</nowiki></code>
This citation is "empty" because the Italian-language parameters {{para|titolo}} and {{para|anno}} are not recognized as valid parameter names on the English Wikipedia.

"Empty citation" may also mean that an editor meant to use another template entirely. Perhaps the editor used {{tlx|citation}} when the intent was to use {{tlx|citation needed}} or {{tlx|quote}}.

To resolve this error, add appropriate parameter identifiers, translate foreign language parameter names to their English equivalents, or replace the CS1/CS2 template with a more appropriate template.
