Hi guys, I’m having a real bug when I rename the slug for activities.
I use the code
define ( 'BP_ACTIVITY_SLUG', 'attivita' );
when I enter the user’s activities, the actions (comments, favorite, delete) are not displayed. I analyzed the page code and noticed that the modified slug is inserted in the code
<div class=" attivita-meta action">
should stay
<div class="activity-meta action">

I deleted the code to translate the slug and everything goes back to normal. Where can I find the template file to edit this div?
The problem is only present on the member activity page. in groups and general activities everything is ok even with the translation of the slug.

Can anyone help me? Have you already encountered this problem?
