https problems and page redirects

Hi there, i recently set up a wordpress blog and i decided to enable https for logins and admin pages, so i followed a blog post here >> https://www.whattheken.com/ on doing so with nginx rewrite rules.

once i enabled this config my problems start, when i try to access any of the pages that should be served as https they are downloaded as a file instead of being rendered, and when i try and access the pages that should be shown as normal http i just get an error in the browser about being in a redirect loop. now i can’t get into my admin pages or anywhere by my site frontpage. my site conf is this

	upstream php {
		server unix:/var/run/php5-fpm.sock;
	}

	## Your only path reference.
