所遇问题现象，论坛有一些帖子不访问，报以下错误：
Discuz! Database Error

(145) Table "./jdhr/security_failedlog" is marked as crashed and should be repaired
SELECT count(*) FROM security_failedlog

pre_security_failedlog 是防水墙失败日志记录表
并且修复此表后过段时间还会问题重现
只能删除表之后重建表才可以
进入 phpMyAdmin 运行以下 SQL 语句即可

  1. DROP TABLE pre_security_failedlog;
  2. CREATE TABLE pre_security_failedlog (
  3.   id int(11) NOT NULL AUTO_INCREMENT,
  4.   reporttype char(20) NOT NULL,
