I think this issue might be common enough to require a topic.
I'm running wordpress 4.2.1, and when ever I load in the demo data, and they try to check out the page, the css and js don't load. I get these errors in the dev tools console log:
I know the theme is supposed to generate these files when hitting Save Changes from the admin console, which I've done, but the files don't get generated for some reason in my /var/www/html/wp-content/themes/calypso folder.
Is it possibly this is a permissions issue. All my wordpress files are currently under root, do I need to create a new user and run wordpress as this user to make it possible to create these files?
