Hi again Brajesh.

Here’s some code that will probably help a lot – the BuddyPress Activity Privacy plug-in has a function to work around Activity Plus’ oddities. Here’s the code it uses (I hope back ticks preserve the code):

if( function_exists('bpfb_plugin_init') ) {

	add_action( 'wp_footer', 'bp_activity_privacy_fix_bp_activity_plus' );
	function bp_activity_privacy_fix_bp_activity_plus() {
	?>
	<script type="text/javascript">

	if ( typeof jq == "undefined" )
		var jq = jQuery;

	jq(document).ready( function() {

		form = jq("#whats-new-form");
		text = form.find('textarea[name="whats-new"]');

		//remove event handler previously attached to #bpfb_submit
		jq("#bpfb_submit").die( "click" );

		jq(document).delegate("#bpfb_submit", 'click', function (event) {

			event.preventDefault();
			var params = _bpfbActiveHandler.get();
			var group_id = jq('#whats-new-post-in').length ?jq('#whats-new-post-in').val() : 0;
			
			jq.post(ajaxurl, {
				"action": "bpfb_update_activity_contents", 
				"data": params, 
				// add visibility level to the ajax post
				"visibility" : jq("select#activity-privacy").val(),
				"content": text.val(), 
				"group_id": group_id
			}, function (data) {
				_bpfbActiveHandler.destroy();
				text.val('');
				jq('#activity-stream').prepend(data.activity);
				/**
				 * Handle image scaling in previews.
				 */
				jq(".bpfb_final_link img").each(function () {
					jq(this).width(jq(this).parents('div').width());
				});

				//reset the privacy selection
				jq("select#activity-privacy option[selected]").prop('selected', true).trigger('change');

				jq('select.bp-ap-selectbox').customStyle('2');
			});
		});
	});

	</script>
	<?php 
	}

}
