所遇問題現象，論壇有一些帖子不訪問，報以下錯誤：
Discuz! Database Error

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

pre_security_failedlog 是防水牆失敗日誌記錄表
並且修復此表後過段時間還會問題重現
只能刪除表之後重建表才可以
進入 phpMyAdmin 運行以下 SQL 語句即可

  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,
