Hi,
Thank you for the patience.

1. Please use this code in your bp-custom.php or in your theme’s functions.php. It will restrict deletion of circles.

add_filter( 'bcircles_user_can_delete_circle', function ( $can ){
	 // only admins can.
	return is_super_admin();
});

2. Please recheck. I have tested it today and these two are working fine. Please make sure the “Create circles” check box is enabled as shown below.

Please do note that the separator is ‘|’ and not ‘/’

3. Please upgrade to 1.0.4. You can enable it from Settings->BuddyCircles -> Miscellaneous section.

Please let me know if works for you or not?

Hi,
Thank you for the question.

The simplest way to achieve it will be via translation. Please use any translation tool(poedit or a plugin) and change the label.

Please let me know if that works for you or not?

Hi,
Please give a try to this

add_action( 'plugins_loaded', function () {
	// remove youtube support.
	wp_oembed_remove_provider( '#https?://((m|www)\.)?youtube\.com/watch.*#i' );
	wp_oembed_remove_provider( '#https?://youtu\.be/.*#i' );
} );

It should most probably work.

Brajesh
