The shortcut [[wikilivres:Main_Page]] is broken now. It's the redirect to https://biblio.wiki, which was deleted.
Could you replace shortcut wikilivres to https://wikilivres.org/wiki/$1? (on [[ru:Special:Interwiki]] and other wikisites)
And remove, or same change, the shortcut bibliowiki.
(For history, there before was site wikilivres.org, it was closed and moved to biblio.wiki, and now moved to wikilivres.org. Details)
