Django 301 and 403 forbidden errors on my static files in production

I’m trying to deploy a django website on a ubuntu 14.04 vps using nginx and gunicorn but my css files and js files are not getting loaded.i developed it on the default django development server and it worked very well, but when i deploy my site and collectstatic and try to access it through the browser only the HTML text gets loaded and on checking on my browser console i find 301 and 403 forbidden errors on my static folder. i a newbie to ubuntu and django as well and all the threads and forums i’ve found online simply point to permissions and ownership of files and haven’t had any luck when i correct my permissions.
