Hi Rikard,
using another method I have activated the Avia Builder in a Custom Type called “Party”, that is not the problem, the single-party.php file is processed well. That’s the code I’ve added in the meta.php file:

add_filter(‘avf_builder_boxes’,’custom_post_types_options’);

function custom_post_types_options($boxes)
{
$boxes[] = array( ‘title’ =>__(‘Avia Layout Builder’,’avia_framework’ ), ‘id’=>’avia_builder’, ‘page’=>array(‘party’), ‘context’=>’normal’, ‘expandable’=>true );
$boxes[] = array( ‘title’ =>__(‘Layout’,’avia_framework’ ), ‘id’=>’layout’, ‘page’=>array(‘party’), ‘context’=>’side’, ‘priority’=>’low’);
return $boxes;
}

The problem is that when I use the advanced editor to add the contents, the single-party.php is not processed any more, and WP just processes the single.php file.

Can you tell me how to use de advanced editor and make the WP process my custom single-party.php?

Best Regards,
Boream.
