Found it.
in child theme i used file from BP 2.x
So i’ve just replaced

				<?php if ( bp_activity_user_can_delete() ) {
					echo '<a href="'.bp_get_activity_comment_delete_link().'" type="button" class="button button-xs item-button bp-secondary-action delete-activity confirm" rel="nofollow"><i class="fa fa-trash-o"></i></a>';
					
					} ?>

with

<?php if ( bp_activity_user_can_delete() ) bp_activity_delete_link(); ?>

Solved

BP legacy – but yes, i have some changes in child theme.
When I disable child theme, it is working…
I’m just wondering where can be the issue…where i should focus to find the trouble…
somewhere in buddypress/activity/ ?
