Greetings,

I recently completed a manual upgrade from 4.0.1 to 4.5.0f. Everything is working fine except for the Documents module. Even though we have about 30 documents in the DB, none of them display in the "document list". Instead, I get this error where the revision history should be:

Error retrieving Document list: Query Failed: SELECT document_revisions.id , document_revisions.filename , document_revisions.revision , document_revisions.date_entered , jt0.user_name created_by_name , jt0.created_by created_by_name_owner , 'Users' created_by_name_mod, document_revisions.change_log , document_revisions.document_id , document_revisions.created_by , 'therevisions' panel_name FROM document_revisions LEFT JOIN users jt0 ON jt0.id= revisions.created_by AND jt0.deleted=0 AND jt0.deleted=0 where ( document_revisions.document_id= 'aa900d29-940e-f61a-45ab-45267f80c7db' AND document_revisions.deleted=0) AND document_revisions.deleted=0 ORDER BY document_revisions.revision desc LIMIT 0,10::MySQL error 1054: Unknown column 'revisions.created_by' in 'on clause'

To a novice user like myself, it looks like a problem in the database that relates to the revision information. I appreciate any insight into what I should do next.
