It looks that when Aragonese projects were set up, we forgot to setup the aliases for their NS_MAIN namespaces, which should be Biquipedia. See also T130599: Change of NS_PROJECT (Wikitionary to Biquizionario) for an.wiktionary, which I fixed some days ago. Waiting for comments from local community for some days before scheduling for SWAT.
