Category:CS1 errors: parameter link

This is a tracking category It is used to build and maintain lists of pages—primarily for the sake of the lists themselves. They are not part of the knowledge base categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

This is a tracking category for CS1 citations that have |param-link= errors.

These link-holding parameters and their matching title-/name-holding parameters are combined to create a working wikilink to a related article.

This error occurs when any of these |<param>-link= parameters contain a wikilink or a URL, or they contain any of the characters not permitted in Wikipedia article titles per WP:TITLESPECIALCHARACTERS (except _ (underscore), used as a replacement for spaces, and #, used as a fragment identifier when linking to article sections). The prohibited characters are: < > [ ] | { }.

The |<param>-link= parameter value should contain only the title of a Wikipedia article or a link to a section of a Wikipedia article. Module:Citation/CS1 checks the |<param>-link= parameter values for wikimarkup and for a URI scheme (http://, https://, the protocol relative scheme //, etc.). Interlanguage links in any of the |<param>-link= parameters require a leading colon:

:fr:Période d'exil de Caravage

While primarily intended to catch the errors mentioned above, Module:Citation/CS1 will also catch malformed interlanguage wikilinks wherever they occur. Interlanguage wikilinks that have the form:

[[fr:Période d'exil de Caravage]]

do not create visible clickable links in the article text. Instead, these links appear in the left pane in the languages list. Module:Citation/CS1 disables interlanguage links in this form and emits an error message. The correct form is:

[[:fr:Période d'exil de Caravage]]

This error can also be caused when:

• there is a |<param>-link= value and the matching |<param>= parameter contains a wikilink.
• |first= and |<param>-first= (and enumerated forms) contain a wikilink

To resolve this error, do one of the following:

• Ensure that the |<param>-link= value is the full name of a Wikipedia article (without brackets) or a section of an article, and not a link to an external web site.
• Make sure that there are no wikilinks in the matching |<param>= parameters.
• If you want to link to a URL outside of Wikipedia, move the link to |url= or a similar parameter, if one is available in the template you are using.

Pages with this error are automatically placed in Category:CS1 errors: parameter link.^[a]
