转换数据后更新缓存出错

我从dvbbs7.1转换成dz5，进后台后更新缓存出现以下代码：

Discuz! info: MySQL Query Error

SQL: SELECT f.fid, f.type, f.name, f.fup, ff.viewperm, a.uid FROM cdb_forums f LEFT JOIN cdb_forumfields ff ON ff.fid=f.fid LEFT JOIN cdb_access a ON a.fid=f.fid AND a.allowview='1' WHERE f.status='1' ORDER BY f.type, f.displayorder
Error: Table 'discuz.cdb_access' doesn't exist
Errno.: 1146

Similar error report has beed dispatched to administrator before.

请问怎么解决，谢谢。。
