MediaWiki:Badtitletext
Appearance
The requested page title is invalid. It may be empty, contain unsupported characters, or include a non-local or incorrectly linked interwiki prefix.
You may be able to fix it by:
- searching for its name (with the interwiki prefix, if any) in the search box.
- clicking this Special:GoToInterwiki link.
Possible causes are:
- an attempt to load a URL such as https://en.wikipedia.org/wiki/| (the | character is unsupported);
- an attempt to load a URL pointing to a "non-local" interwiki page (usually those not run by the Wikimedia Foundation). For example, the URL https://en.wikipedia.org/wiki/meatball:WikiPedia will give this error, because the "meatball:" interwiki prefix is not marked as local in the interwiki table. Certain interwiki prefixes are marked as local in the table. For example, the URL https://en.wikipedia.org/wiki/meta:Main_Page can be used to load meta:Main_Page. All interlanguage prefixes are marked as local, and thus URLs such as https://en.wikipedia.org/wiki/fr:Accueil will work as expected. However, non-local interwiki pages can still be accessed by interwiki linking or by entering them in the search box. For example
[[meatball:WikiPedia]]
can be used on a page, like this: meatball:WikiPedia.
