Since last update I'm getting this error, no matter what calification am I giving to the post:
NaN/5 (For the first try)
0/5 (For the second try)
And after that the option to give a rating deactivates. I try delete the plugin and reinstall and have the same problem.
Another thing is a suggestion for unique rating, adding "based on user ID", this would be excellent for "just logged in users can rate".
Thanks for your help and for this awesome plugin!
