Hi Carsten,
This works fine for me.

add_action( 'wp', function () {
	bp_core_remove_subnav_item( 'profile', 'public' );
} );

Please do note that it will break access to user’s profile view as the ‘public’ is the default sub nav for profile.
Also, here is a slightly better version to avoid fatal errors when BP is disabled.

add_action( 'wp', function () {
	if ( function_exists( 'bp_core_remove_subnav_item' ) ) {
		bp_core_remove_subnav_item( 'profile', 'public' );
	}
} );

Just had a look at your screenshot and you can see the last rule is forcing 50px.

Hi Ivan,
Thank you for reporting the issue.

Can you please confirm it is our plugin? I could not find any purchase for this plugin from your account and just thinking that it may not be ours.

Please confirm and we will test ours.

Hi Tosin,
Thank you for the question.
At the moment, we are using default WordPress uploader/editor and we haven’t added any setting for it.

We will add something on this line in one of our future release.
In the mean time, Please give it a try.
