I recently upgraded two live sites and the test site on my local machine from 4.6.0 to 4.6.1, after doing this whenever an anonymous user tries to access a node that has had permissions set to authenticated they receive a “Page not found” message instead of “Access denied”.

I have since upgraded to 4.6.2 with not change to the situation, this problem can be seen at www.avondescent.com.au (select competitors) and www.clubswa.com.au (select members only).

Any assistance at all with this would be greatly appreciated.
