MediaWiki:Config-connection-error/qqq

$1 is the external error from the database, such as "DB connection error: Access denied for user 'dba'@'localhost' (using password: YES) (localhost)."

If you're translating this message to a right-to-left language, consider writing $1. . (When the bidi features for HTML5 will be implemented in the browsers, it will probably be a good idea to write it as $1. .)
