Hello Klaus,
We apologize for not being able to respond earlier.
Unfortunately, this is a bug of pt theme add-on plugin and we will be resolving it soon in our next update.
We are sorry for the inconvenience you may be facing.
In the meantime, if you need to implement this now, you can do this via adding a filter.
Open your theme’s function file and past below code at end of the file.
add_filter('pre_get_posts', 'custom_post_type_tags');
if (!function_exists('custom_post_type_tags'))
{
function custom_post_type_tags($query) {
if(is_tax('ptta-portfolio-categories')) {
$post_type = 'ptta-portfolio';
$query->set( 'post_type', array( 'post', $post_type ) );
return $query;
}
elseif(is_tax('ptta-testimonials-categories')) {
$post_type = 'ptta-testimonials';
$query->set( 'post_type', array( 'post', $post_type ) );
return $query;
}
elseif(is_tax('ptta-team-categories')) {
$post_type = 'ptta-team';
$query->set( 'post_type', array( 'post', $post_type ) );
return $query;
}
}
}
Thank you
Regards,
