求助！！SS7.0升级到7.5后，经常出现如下错误

SupeSite info: MySQL Query Error

User: 风
Time: 2010-7-21 11:16am
Script: /admincp.php

SQL: SELECT dateline, subject, itemid, type, username, uid FROM [Table]spaceitems WHERE folder='1' AND dateline>'1279555200' AND dateline<'1279641600' ORDER BY dateline
Error: Unknown column 'folder' in 'where clause'
Errno.: 1054

这样类似的错误在很多页面都会出现

部分数据表不完整

使用tools修复数据库试试。
