在检查wordpress网站中的错误日志时，我会得到以下mysql日志。
161120 6:41:58 InnoDB: cannot calculate statistics for table databasename/wp_wfHoover
InnoDB: because the .ibd file is missing. For help, please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.5/en/innodb-troubleshooting.html
161120 6:41:58 [ERROR] MySQL is trying to open a table handle but the .ibd file for
table databasename/wp_wfHoover does not exist.
Have you deleted the .ibd file from the database directory under
the MySQL datadir, or have you used DISCARD TABLESPACE?
See http://dev.mysql.com/doc/refman/5.5/en/innodb-troubleshooting.html
这是什么问题？我的网站使用apache2托管在ubuntu服务器上。
提前致谢
