这个MySQL语法有什么错误？

这里怎么了

我从本地pma导出此表，并尝试将其上载到远程服务器

CREATE TABLE IF NOT EXISTS `posts` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `date` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `banna` text COLLATE utf8_croatian_ci,
  `bannb` text COLLATE utf8_croatian_ci,
  `img` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `images` text COLLATE utf8_croatian_ci,
  `title` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `subtitle` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `story` mediumtext COLLATE utf8_croatian_ci,
  `status` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `tags` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `auth` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `moder` varchar(255) COLLATE utf8_croatian_ci DEFAULT NULL,
  `linked` json DEFAULT NULL,
  `inde` int(11) DEFAULT NULL,
  `count` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=382 DEFAULT CHARSET=utf8 COLLATE=utf8_croatian_ci

错误：

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'json DEFAULT NULL,
  `inde` int(11) DEFAULT NULL,
  `count` int(11) DEFAULT NULL' at line 15

我已经在mysql版本5.7.21上运行了您的查询，它工作正常，没有抛出错误，所以在我看来您的站点中出现了与mysql版本相关的问题，下面是执行结果

CREATE TABLE IF NOT EXISTS `posts` (
  `id`       bigint(20) NOT NULL                   AUTO_INCREMENT,
  `date`     datetime   NOT NULL                   DEFAULT CURRENT_TIMESTAMP,
