Hi, everybody, I think I have a problem (I don't know how serious) related to the DB schema of my wiki (tunearch.org). Having said that everything seems to work correctly (navigate, search, edit, …), If I run php cleanupUsersWithNoId.php --force --prefix=* the program works only with the revision table for archive, logging, image, oldimage, filearchive, ipblocks and recentchanges tables I get an error similar to this: =============== Beginning cleanup of archive Wikimedia\Rdbms\DBQueryError from line 1603 of /var/www/w/includes/libs/rdbms/database/Database.php: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading? Query: SELECT  ar_id,ar_user,ar_user_text,ar_id  FROM `archive`    WHERE (1=1)  ORDER BY ar_id LIMIT 100  Function: CleanupUsersWithNoId::cleanup Error: 1054 Unknown column 'ar_user' in 'field list' (localhost) and this backtrace. =============== #0 /var/www/w/includes/libs/rdbms/database/Database.php(1574): Wikimedia\Rdbms\Database->getQueryExceptionAndLog('Unknown column ...', 1054, 'SELECT  ar_id,a...', 'CleanupUsersWit...') #1 /var/www/w/includes/libs/rdbms/database/Database.php(1152): Wikimedia\Rdbms\Database->reportQueryError('Unknown column ...', 1054, 'SELECT  ar_id,a...', 'CleanupUsersWit...', false) #2 /var/www/w/includes/libs/rdbms/database/Database.php(1807): Wikimedia\Rdbms\Database->query('SELECT  ar_id,a...', 'CleanupUsersWit...') #3 /var/www/w/includes/libs/rdbms/database/DBConnRef.php(68): Wikimedia\Rdbms\Database->select('archive', Array, Array, 'CleanupUsersWit...', Array) #4 /var/www/w/includes/libs/rdbms/database/DBConnRef.php(315): Wikimedia\Rdbms\DBConnRef->__call('select', Array) #5 /var/www/w/maintenance/cleanupUsersWithNoId.php(153): Wikimedia\Rdbms\DBConnRef->select('archive', Array, Array, 'CleanupUsersWit...', Array) #6 /var/www/w/maintenance/cleanupUsersWithNoId.php(63): CleanupUsersWithNoId->cleanup('archive', Array, 'ar_user', 'ar_user_text', Array, Array) #7 /var/www/w/maintenance/Maintenance.php(1746): CleanupUsersWithNoId->doDBUpdates() #8 /var/www/w/maintenance/doMaintenance.php(99): LoggedUpdateMaintenance->execute() #9 /var/www/w/maintenance/cleanupUsersWithNoId.php(212): require_once('/var/www/w/main...') #10 {main} —— I ran cleanupUsersWithNoId.php to then run migrateActors.php because an error received during the installation of an extension (e.g. Extension:Comments) suggested that I had not run my "application's database schema updater after upgrading".
