Unknown column 'a.ID_ATTACH' in 'field list'

[Hans v. M.]

Have converted my Yabbse 1.5.5 forum. In the new smf forum all messages seem to be there, but when I go further and try to log in it says Unknown column 'a.ID_ATTACH' in 'field list'.
What did I do wrong? And, of course :-) what could I do to fix this?
Thanks, Hans

EDIT: I changed yabbse_ in backup_yabbse_ and not I get the error : Unknown column 'a.ID_ATTACH' in 'field list'

Please run this query in phpMyAdmin:

SHOW CREATE TABLE yabbse_attachments;

Are you sure you ran upgrade.php properly?  Sounds like you have a YaBB SE database, or you upgraded without the old YaBB SE settings in your Settings.php.
