i have encounter this problem. u can use the phpmyadmin to see the status of the bb_post/bb_topic/bb_post_text. if it's "in use". select the table and use phpmyadmin repair them.
hi i don't think this site have so many user online since it doesn't match it's alexa rank.acording to the alexa rank it have about 10000ip/day less than xoops.org.
Sometimes i have to ban someone from forum then i trun them to a new group. but they still can post untill next login. how to make the group change take effect immediately?
