@portofacil Plesk forum is a good idea and I know this forum is for EasyEngine users but the problem isn't related with Plesk I have WordPress without Nginx cache on the same machine and it doesn't have any problem. I think it's a Nginx configuration problem but I don't have enough experience with Nginx so I just hoped I can find somebody in here who solved this problem before.
Nevertheless, I'll open a topic at Plesk forum too but I think I have more chance with this forum.
Thanks for the response.
