我在mariadb 10.2.7中使用xampp,我安装了一个seo模块,然后使用json,它显示了以下错误。

Error: Uncaught Exception: Error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'rows' at line 1<br />Error No: 1064<br />SELECT FOUND_ROWS() as rows in C:\xampp\htdocs\store\system\library\db\mysqli.php:40
