I am working on a fresh multilingual instalment of Mediawiki. I want to use one database containing 2 languages and some shared tables containing user data. Here is the LocalSettings.php which is used for one of the aforementioned installations: ## Database settings $wgDBtype = "mysql"; $wgDBserver = "localhost"; $wgDBname = "wiki_db"; $wgDBuser = "wiki_user"; $wgDBpassword = "_OMITTED_"; # MySQL specific settings $wgDBprefix = "en_"; # MySQL table options to use during installation or update $wgDBTableOptions = "ENGINE=InnoDB, DEFAULT CHARSET=binary"; # Shared database table $wgSharedDB = 'wiki_db'; $wgSharedTables[] = 'actor'; $wgSharedPrefix = 'shared_'; The problem is that no shared table is created. What am I doing wrong?
