I see this when I select 'expand' from a board index.

SQL ERROR: Unable to do_query: SELECT B_Number,B_Parent,B_Posted,B_Username,B_Subject,B_Status,B_Approved,B_Icon,B_Reged,B_Color,B_UStatus FROM w3t_Posts WHERE B_Main = 45345 AND B_Number <> 45345 AND t1.B_Approved = 'yes' ORDER BY B_Number Desc
