Conflict with WordPress Customizer

Hi! I read some closed topics about the Customizer broken with Navception.
This solution worked for me:

On lines 144 and 145 from navception.php change

$navception_item->ID .= $navception_suffix;
$navception_item->db_id .= $navception_suffix;

to

$navception_item->ID;
$navception_item->db_id;
