每次加载一个页面时，我都会多次收到此消息[2018年7月7日17:30:49 utc]wordpress数据库错误您的sql语法有错误；请查看与您的mysql服务器版本对应的手册，以了解在第6行使用near'和p.post\u status='publish''的正确语法，以便从wp\u posts p查询选择count（*）

[07-Jul-2018 17:30:49 UTC] WordPress database error 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 'AND p.post_status='publish'' at line 6 for query SELECT count(*) FROM wp_posts p

我想这会导致geomashup的“geomashupdb.php”的一部分（复制到下面），我读了一些关于id/id之间大小写不匹配的内容，但是我似乎找不到任何这样的例子。任何帮助或建议都会很好。
