Code:
		$db->query("
            ALTER TABLE xf_template ADD template_modified MEDIUMTEXT NULL  COMMENT 'TMS' AFTER template ,
            ADD template_modifications MEDIUMBLOB NULL COMMENT 'TMS' AFTER template_modified
        ");
Either another addon uses that column or TMS was previous installed. You can manually remove that column from the database.
