Thank you.
I tested it and I am not sure why but it seems this code in mpp.js is not triggering on your site when we post update

   //filter ajax request but only if the activity post form is present
	if( jq( '#whats-new-form' ).get(0) ) {
		
		
		jQuery( document ).ajaxSend(function( event, jqxhr, settings ) {
			
			if( is_post_update( settings.data ) ) {
				var attached_media = mpp_get_attached_media();
				
				if( attached_media ) {
					settings.data = settings.data+ '&mpp-attached-media='+attached_media;
					mpp_reset_attached_media();
				}
			}
		});
		
		

The above code includes uploaded media ids in the post. I checked using mpp_get_attached_media() helper function in console and uploaded media ids are attached but the above code is not triggering and that is causing the problem.

Can you think of something on the site that might be causing it?

Hi Lavish,
Most probably you tested it while you were logged in as admin. Please try testing it with normal user accounts.

Admins can mention anyone.

Hi Lavis,
That is another approach for navigation but using po/mo is still preferred way. If it is not working, Please create a bug report on BuddyPress trac.

Thank you. It needs some work on editing reply etc, allow deleting.

I am looking forward to your contributions.

Hi Tony,
Welcome to BuddyDev and thank you for posting.

The problem with [mpp-uploader] is that it needs a gallery to be present for the user. If it is not working for sopme users, They may not have a gallery. There are multiple solutions to this.

1. Are you going to us Sitewide gallery or BuddyPress members Gallery?
2. Once you will let me know above, we can automatically create a gallery for the current user(using some code) if they don’t have any and they will be able to upload.

Thank you
