We have a Drupal 7 Drupal Commerce site that we've just moved to our virtual private apache server, however we're seeing very strange behaviour that's making the site not work.

We're getting a strange problem where many files (images, CSS, JS) are getting "307: Temporary redirect"s to 'index.html', which doesn't even exist.

We have a very ordinary apache setup (no unusual settings), and the htaccess file of our website is straight from Drupal core - we haven't edited ourselves.

Is this a problem with the way we've set up Drupal, apache, DNS, or something else?
