Changing Theme in wordpress not working.
I've been trying to change to any other theme in Wordpress. I'm fairly new to this sort of thing and have just been following the tutorials to get anything done.
I have installed wordpress the long way (Apache, LAMP etc etc) and have just followed this one to get a secure upload (theme) https://www.digitalocean.com/community/tutorials/how-to-configure-secure-updates-and-installations-in-wordpress-on-ubuntu
However, now when I click to install a theme I get "The uploaded file could not be moved to wp-content/uploads/2014/09."
I've tried a lot of things even things posted in the comments of the linked section.
Can someone please help me out with this one?
