Hi Isabel,
I am sorry, I am not familiar with your theme, so unable to provide an exact answer.

I need to know how to determine the listing profile of a user if id or username is given.

I ma posting a sample code in which redirection is commented, Please feel free to adapt it based on how the listing works on your site.

add_action( 'bp_template_redirect', function () {
	if ( ! bp_is_user() ) { // replace with bp_is_my_profile() to only do it for own profie.e
		return;//
	}
	// Use the id or dimain
	// bp_displayed_user_id();
	// bp_displayed_user_username();
	// where do you want to redirect.
	// $url = '';

	// bp_core_redirect( $url );
} );

Hope that helps.

Hi Audiomonk,
To set the default status globally, Please visit Dashboard->MediaPress->settings.

For existing Gallery and Media, you will need to change it manually. Changing the gallery permission will not make a private media public. You will need to edit it (you can bulk edit from gallery page) for the media too.
