title: Prestashop 1.7 /admin error 500
body: <p>I just installed PrestaShop 1.7.2.0 and I'm getting error 500 when I'm trying to access <em>/admin</em>.
  My admin folder on FTP is renamed to <em>admin[random_string]</em> (how? why?). Frontend seems to be working ok.</p>
  
  <p>When I remove <em>/admin/.htaccess</em> I get 404, when I put it back, I get 500. I did change anything inside of it.</p>
  
  <p>What could be a problem?</p>
