Displaying more than 10 items on portfolio archives

Hi team,

I can’t seem to set the array in taxonomy-portfolio_entries.php to display more than 10 entries per page. Other settings (pagination for example) do take effect.

I have:

$grid = new avia_post_grid(array(	'linking' 	=> '',
                                                        'columns' 	=> '1',
                                                        'items' => 20,
                                                        'contents' 	=> 'title',
                                                        'sort' 		=> 'no',
                                                        'paginate' 	=> 'yes',
                                                        'set_breadcrumb' => false,
                                                ));
                    $grid->use_global_query();

Could you give me a pointer?

Many thanks,
Joe
