Why are avatars not showing up?

Question

DLE

Hello everyone, I rummaged through the entire template, but I still don’t understand what the problem is, user avatars are not displayed, the rights to the fotos 777 folder are, everything seems to be fine in the template, how to fix it?
if I'm not mistaken, then this code is responsible for displaying the avatar.

<ul class="list-inline" style="font-size: 13px;margin: 0px 0 0px 0;">
  <li> <img cass="hidden-sm" src="{foto}" onclick="ShowProfile('{login}', '{login}', '1'); return false;" alt="{login}" style="width: 28px;
