这种MySQL语法有什么问题？

Question

What is wrong here?

I exported this table from my local pma and trying to upload it on remote sever.

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

Error:

#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

I have run your query on mysql version 5.7.21, it works fine, No error thrown, so it seems to me mysql version related issue raised in your site, here is the execution result
