添加表 pre_forum_threadlog 出错,请手工执行以下SQL语句后,再重新运行本升级程序: CREATE TABLE pre_forum_threadlog ( tid mediumint(8) unsigned NOT NULL DEFAULT '0', fid smallint(6) unsigned NOT NULL DEFAULT '0', uid mediumint(8) unsigned NOT NULL DEFAULT '0', otherid smallint(6) unsigned NOT NULL DEFAULT '0', `action` char(10) NOT NULL, expiry int(10) unsigned NOT NULL DEFAULT '0', dateline int(10) unsigned NOT NULL DEFAULT '0', PRIMARY KEY (tid,fid,uid), KEY dateline (dateline) ) ENGINE=MYISAM DEFAULT CHARSET=gbk

安装一下PHPMYADMIN，选中你的数据库在SQL中执行：

1. CREATE TABLE pre_forum_threadlog ( tid mediumint(8) unsigned NOT NULL DEFAULT '0', fid smallint(6) unsigned NOT NULL DEFAULT '0', uid mediumint(8) unsigned NOT NULL DEFAULT '0', otherid smallint(6) unsigned NOT NULL DEFAULT '0', `action` char(10) NOT NULL, expiry int(10) unsigned NOT NULL DEFAULT '0', dateline int(10) unsigned NOT NULL DEFAULT '0', PRIMARY KEY (tid,fid,uid), KEY dateline (dateline) ) ENGINE=MYISAM DEFAULT CHARSET=gbk
