SQLSTATE[42S22]: Column not found: 1054 Unknown column

Hello,

I’ve got this error on the browser directly. How can I fix it?

{"code":"42S22","file":"\/var\/www\/html\/dmxConnectLib\/lib\/db\/Connection.php","line":86,"message":"SQLSTATE[42S22]: Column not found: 1054 Unknown column 'idusers' in 'field list'","trace":"#0 \/var\/www\/html\/dmxConnectLib\/lib\/db\/Connection.php(86): PDO->prepare('SELECT `idusers...')\n#1 \/var\/www\/html\/dmxConnectLib\/lib\/auth\/DatabaseProvider.php(68): lib\\db\\Connection->execute('SELECT `idusers...', Array)\n#2 \/var\/www\/html\/dmxConnectLib\/lib\/auth\/Provider.php(150): lib\\auth\\DatabaseProvider->permissions(16, Array)\n#3 \/var\/www\/html\/dmxConnectLib\/modules\/auth.php(64): lib\\auth\\Provider->restrict(Object(stdClass))\n#4 \/var\/www\/html\/dmxConnectLib\/lib\/App.php(173): modules\\auth->restrict(Object(stdClass), NULL)\n#5 \/var\/www\/html\/dmxConnectLib\/lib\/App.php(137): lib\\App->execSteps(Object(stdClass))\n#6 \/var\/www\/html\/dmxConnectLib\/lib\/App.php(107): lib\\App->execSteps(Array)\n#7 \/var\/www\/html\/competition_event_vote.php(19): lib\\App->exec(Object(stdClass), true)\n#8 {main}"}
