I suspect something is wrong with your dbname switching.. The build script uses maintenance/dumpBackup.php of your MediaWiki installation to make the dump (this is where the red-highlighted bit comes from) - you need to make sure this works for all of your alternative wikis. -- 23:46, 18 February 2011 (UTC)
