i tried from my admin account and from my regular member account and both times when I tried to rate a user's picture it just refreshed the page basically and the rating doesn't get recorded.
cannabishq.com/cop/index.php
works fine for me - I rated http://cannabishq.com/cop/displayimage.php?pos=-24 with three stars, which displays just fine.
can admin's rate?
Depends if you allow them to on the groups page.
On the groups page i have it set so admins can rate. But i still cannot rate :-\
I tried logging in as a normal user account and it didnt work, and i tried as a guest and it didnt work.
Could it be because i'm using Mozilla Firefox?
must be on your end, I was able to vote just fine (http://cannabishq.com/cop/displayimage.php?pos=-34), using Firefox
