title: ERR_TOO_MANY_REDIRECTS in backoffice when running Prestashop in Docker
body: <p>I'm trying to make a docker environment for a Prestashop project. I have it almost working but for some reason, the back office is inaccessible - it gives me a ERR_TOO_MANY_REDIRECTS error.</p>
  
  <p>I changed the urls in <code>shop_url</code> table and changed PS_SHOP_DOMAIN and PS_SHOP_DOMAIN_SSL to no vain. I tried to disable friendly URLs, enable/disable SSL - but the problem persists.</p>
  
  <p>I'm using a custom image for a webserver:</p>
  
  <p><code>luken-wodby-nginx-prestashop</code> Dockerfile:</p>
  
  <pre><code>FROM wodby/nginx:1.10
  
  ENV WODBY_DIR_FILES /mnt/files
  
  RUN rm /etc/gotpl/default-vhost.conf.tpl &amp;&amp; \
      mkdir -p $WODBY_DIR_FILES &amp;&amp; \
      mkdir -p /var/log/nginx
  
  COPY prestashop.conf.tpl /etc/gotpl/
  COPY init/* /docker-entrypoint-init.d/
  </code></pre>

  <p>Website works just fine, only the back office is inaccessible and gives ERR_TOO_MANY_REDIRECTS error.</p>
  
  <p>Any ideas what can be wrong?</p>
