I upgraded threads from 6.44 to 6.5.2, uploaded the mod'd files for sub forums and now I get..

/*Script:* /home/website/public_html/testboard/ubbthreads.php
*Line#:* 296
*SQL Error:* Unknown column 'Cat_Entry' in 'field list'
*SQL Error #:* 1054
*Query:* SELECT Cat_Title,Cat_Entry,Cat_Description FROM w3t_Category
WHERE Cat_Type = 'forum' ORDER BY Cat_Number /

This board had sub forums previously, so not sure what is wrong.

Halp..
