Hallo, Antoine,

(dbxy.example.com)".
It looks like this is a table from the CheckUser
extension. Have you
installed that extension recently? It definitely need some databases
tables which can be automatically created using
maintenance/update.php from the command line. That script should take
care of "upgrading" your database schema.
Bingo! Thank you!
Viele Gruesse!
