Hello friend!

You will need to do just a bit more configuration to be able to use permalinks with Nginx. This handles itself with Apache as Wordpress writes the instructions to a .htaccess file, but Nginx does not read that and instead will require manual adjustment. I found a guide that should help you to complete it:
