// Add Avia Builder to Popup Maker
function avf_alb_supported_post_types_mod( array $supported_post_types )
{
$supported_post_types[] = "popup";
return $supported_post_types;
}
add_filter('avf_alb_supported_post_types',
'avf_alb_supported_post_types_mod', 10, 1);

This code made the advanced layout editor button appear when editing the popup, but then it does not work, the popup is empty also if i build a layout.
I tried also with this older code that i found here on the forums:

`function add_builder_to_posttype($metabox)
{
foreach($metabox as &$meta)
{
if($meta[‘id’] == ‘avia_builder’ || $meta[‘id’] == ‘layout’)
{
$meta[‘page’][] = ‘popup’; /*Using ‘ as quotes*/
}
}

return $metabox;
}

But this does nothing.. does not even show the blue advanced editor button

So? What should we do?
