Delete a tabela bans na sua database, em seguida, após ter certeza que ela foi deletada, faça essa consulta sql:
Se sua dtb for SQLITE:
CREATE TABLE "bans" (
"id" INTEGER PRIMARY KEY NOT NULL,
"type" INTEGER NOT NULL,
"value" INTEGER NOT NULL,
"param" INTEGER NOT NULL DEFAULT 4294967295,
"active" BOOLEAN NOT NULL DEFAULT 1,
"expires" INTEGER NOT NULL,
"added" INTEGER NOT NULL,
"admin_id" INTEGER NOT NULL DEFAULT 0,
"comment" TEXT NOT NULL,
"reason" INTEGER NOT NULL DEFAULT 0,
"action" INTEGER NOT NULL DEFAULT 0,
"statement" VARCHAR(255) NOT NULL DEFAULT ''
);
Se for MYSQL:
DROP TABLE IF EXISTS `bans`;
CREATE TABLE `bans`
(
`id` INT UNSIGNED NOT NULL auto_increment,
`type` TINYINT(1) NOT NULL COMMENT '1 - ip banishment, 2 - namelock, 3 - account banishment, 4 - notation, 5 - deletion',
`value` INT UNSIGNED NOT NULL COMMENT 'ip address (integer), player guid or account number',
`param` INT UNSIGNED NOT NULL DEFAULT 4294967295 COMMENT 'used only for ip banishment mask (integer)',
`active` TINYINT(1) NOT NULL DEFAULT TRUE,
`expires` INT NOT NULL,
`added` INT UNSIGNED NOT NULL,
`admin_id` INT UNSIGNED NOT NULL DEFAULT 0,
`comment` TEXT NOT NULL,
`reason` INT UNSIGNED NOT NULL DEFAULT 0,
`action` INT UNSIGNED NOT NULL DEFAULT 0,
`statement` VARCHAR(255) NOT NULL DEFAULT '',
PRIMARY KEY (`id`),
KEY `type` (`type`, `value`),
KEY `active` (`active`)
) ENGINE = InnoDB;
Faça um teste e veja se funciona, se não funcionou comente nesse tópico ;x
