    Hello gbose,

    It is looks like are set incorrectly indexes (pagenum, pagesize). Could you check what data you receive there and is this a correct?
    Also I would like to suggest you one article, that could be useful:
    http://www.jqwidgets.com/jquery-widgets-documentation/documentation/phpintegration/bind-jquery-grid-to-mysql-database-using-php.htm?search=ph
    and this one:
