I have problem with Permissions

Hey guys, I’ve been using Grav for a few weeks now and love it from a custom content type perspective but getting this installed on a server has been a big pain unfortunately. I’m using Digital Ocean to host it and now have it installed and running, but I am not able to post anything as I am getting a permissions error:

Creating directory '/var/www/website.com/public_html/user/pages/03.blog/post2' failed on error mkdir(): Permission denied

I checked the directories and it looks like the correct permissions is being set, I even opened it all the way up (777) and still had the issue…

What else could be going on?
