Hi,
In HikaShop 2.3.4 ; the option "Add to cart popup size" allow you to change the popup size of the "add to cart notice message".
So there is no more line
echo '<div style="display:none;"><a rel="{handler: \'iframe\',size: {x: 480, y: 140}}" id="hikashop_notice_box_trigger_link" href="'.hikashop_completeLink('checkout&task=notice'.$url_itemid,true).'"></a></div>';
In HikaShop 2.3.4 ; we got
$config =& hikashop_config();
$popupWidth = $config->get('add_to_cart_popup_width','480');
$popupHeight = $config->get('add_to_cart_popup_height','140');
echo '<div style="display:none;">'.
'<a rel="{handler: \'iframe\',size: {x: '.$popupWidth.', y: '.$popupHeight.'}}" id="hikashop_notice_box_trigger_link" href="'.hikashop_completeLink('checkout&task=notice&cart_type=cart'.$url_itemid,true).'"></a>'.
'<a rel="{handler: \'iframe\',size: {x: '.$popupWidth.', y: '.$popupHeight.'}}" id="hikashop_notice_wishlist_box_trigger_link" href="'.hikashop_completeLink('checkout&task=notice&cart_type=wishlist'.$url_itemid,true).'"></a>'.
'</div>';
But, if you got a plugin which make an override for the function "hikashop_popup_render" (around 3 lines above in the cart helper) ; you won't process the code in the cart helper but in the plugin itself.
Regards,
