Hi Carsten,
That’s exactly what I mentioned in my previous reply.

You can not remove a default sub nav without forcing another default.
‘public’ is the default profile sub nav and you are removing it causing 404. If you are getting redirected to somewhere else, you may have a 404 redirection enabled.

Hi Carsten,
That’s strange. The who’s online widget takes dimensions of thumbnail, so that should have worked. I will ask @ravisharma to test and assist.

Hi Ivan, Tomas,
Thank you both for your patience.
We will be updating the plugin and not provide custom code.

Hi Tosin,
Thank you for the question.

You may try the following.

add_action( 'bblpro_ppp_purchased_post_expired', function ( $post_id ) {

	$post_type = get_post_type( $post_id );
	if ( 'post' !== $post_type ) {
		return;
	}
	wp_remove_object_terms( $post_id, 'Sponsored Posts', 'content_type' );
} );

Also, you may change the term name with the term slug for better result.

Regards
Brajesh
