各位架站的高手，我把phpbb2架好之後，然後進行測試，在修改個人資料的部份，按送出，卻出現如下的問題，請問我該如何解決？

Could not update user table

UPDATE phpbb_users SET user_nickname = '', user_realname = 'test', user_viewwebsite = '1', user_viewmessanger = '1', user_viewreal = '1', user_website = '', user_icq = '', user_aim = '', user_msnm = '', user_yim = '', user_gender = '0', user_birthday = '0', user_from = '', user_from_flag = 'blank.gif', user_occ = '', user_interests = '', user_home_phone = '', user_home_fax = '', user_work_phone = '', user_work_fax = '', user_cellular = '', user_pager = '', user_last_birthday = 0 WHERE user_id = 2
