it seems that when the ForumName_A_TOPICS table is created it doesnt create a cell for T_ISEVENT , which causes the archives to break.
i added the field T_ISEVENT to ForumName_A_TOPICS and it works.
can someone tell me where [page & line number] the code is that moves the topics from the ForumName_TOPICS to the ForumName_A_TOPICS so i can make sure it takes the T_ISEVENT too.
