Paperclip in Rails, can't upload picture. Previously was ok.

Question

I got this some kind of permission error in my log. Everything was working fine previously, I have tested the photos controller of mine, and it worked well. So I started working on other controllers. Then somehow I found this error happening. Appreciate if someone could help.

Never mind, found out that it was referring to the public/system symbolic link which I deleted earlier. Problem solved now. Thanks.
