CPT on avia builder

Guess you had to know the exact post-type of your CPT
f.e. tribe_events or event etc. pp.

then you can register this post-type for the advanced layout builder:

function avf_alb_supported_post_types_mod( array $supported_post_types ) {
  $supported_post_types[] = 'tribe_events';
  return $supported_post_types;
}
add_filter('avf_alb_supported_post_types', 'avf_alb_supported_post_types_mod', 10, 1);

can you try that first.

maybe this is an option too:

function enable_boxes_on_elements($boxes) {
$boxes[] = array( 'title' =>__('Avia Layout Builder','avia_framework' ), 'id'=>'avia_builder', 'page'=>array('page', 'post', 'portfolio', 'alb_custom_layout'), 'context'=>'normal', 'expandable'=>true );
$boxes[] = array( 'title' =>__('Layout','avia_framework' ), 'id'=>'layout', 'page'=>array('page', 'post', 'portfolio', 'alb_custom_layout'), 'context'=>'side', 'priority'=>'low');
    return $boxes;
}
add_filter('avf_builder_boxes','enable_boxes_on_elements');

change the alb_custom_layout to your post-type you like to add.
