It might be a good idea to put your site through validator.w3.org/nu and also use your browser Developer Tools (Network tab). Scary!

Thank you for your answer Ceford, we did that but we don't see something specific that will lead us to the solution.

We know it has to do with the nginx configuration in our server, maybe some missing library or different values on our server and try to figure it out.

Session Path Writable: No Should be yes.
Open Base: /var/www/vhosts/allyou.gr/:/tmp/ Normally this would be empty.
