Username.org Ripped Theme 23 Nov 2019

I have a problem with this forum: everything is installed ok except for the avatar posts in the index: when there is a new post, in the home index you have to appear next to your avatar post, my avatar always appears in all posts, even the ones not mine ... ditto if I log in with another user, the avatar of who is logged in always appears in the posts, how do I solve?
