Error message: Uncaught exception 'Exception' with message 'DB Error: can not create...

My statusnet instance was fine for several months. But now, I get for a few days the following message (that you can see on my home page as well : http://stocker-partager.fr/statusnet) :

"Fatal error: Uncaught exception 'Exception' with message 'DB Error: can not create' in /home3/olivftp/public_html/statusnet/lib/mysqlschema.php:245 Stack trace: #0 /home3/olivftp/public_html/statusnet/lib/mysqlschema.php(464): MysqlSchema->createTable('notice_to_statu...', Array) #1 /home3/olivftp/public_html/statusnet/plugins/TwitterBridge/TwitterBridgePlugin.php(409): MysqlSchema->ensureTable('notice_to_statu...', Array) #2 /home3/olivftp/public_html/statusnet/lib/event.php(105): TwitterBridgePlugin->onCheckSchema() #3 /home3/olivftp/public_html/statusnet/lib/statusnet.php(199): Event::handle(Array, Array) #4 /home3/olivftp/public_html/statusnet/lib/statusnet.php(116): StatusNet::initPlugins('CheckSchema') #5 /home3/olivftp/public_html/statusnet/lib/common.php(157): StatusNet::init() #6 /home3/olivftp/public_html/statusnet/index.php(47): require_once('/home3/olivftp/...') #7 {main} thrown in /home3/olivftp/public_html/statusnet/lib/mysqlschema.php on line 245"

What could be the cause ? How could I fix it ?

Thanks !
