  <p>So, after checking and re checking, django-site is in the installed apps list, <code>site_id = 1</code> ; my database works except for some images problems.. Well then I tried to do some migrations but this error keep on running and I am now desperate on finding the issue.</p>
  
  <p>Does someone has a clue about it ?</p>
