I just started my adventure with silverstripe. I built new website I'm really excited about this software. First problems appear when I wanted move finished website on VPS server which is running on nginx environment first problem after migration on back end its displaying bad gateway. Second problem url on home page are generated with index.php in the middle on rest pages they are generate url friendly. I've heard nginx+plesk is a pain with configuration but I have no option to change hosting. I tried setup apache but no luck I'm not great with linux. I followed those tutorials: https://www.howtoforge.com/running-silverstripe-on-nginx-lemp-on-debian-wheezy-ubuntu-13.04
https://docs.silverstripe.org/en/3.2/getting_started/installation/how_to/configure_nginx/ <-- this official documentation is a joke sorry.
