[Solved] A non-numeric value encountered in VS 7.1.4

@asti It is not specific to my site. I just tested on a brand new site with nothing on it. I now have this problem on 3 websites. After further troubleshooting, I have found the problem. You should be able to replicate it on your end and update the Wpdiscuz plugin to fix it.

Create a form or edit the default form and use multiple custom rating fields with it. Set "allow post rating" to no in the form. Create a post and use the shortcode [wpdrating show-average = false] with that post. Publish the post. Leave a comment on the post that gives ratings for each field. Publish the comment. You will then see the averages for each custom rating field in the post. Everything looks fine and is working as it should at this point. Now go to the Wordpress dashboard to manage your comments. Delete the comment with the ratings that you just published. Return to the post you created on the front end and the previously reported error will be there. Furthermore, you'll see NAN shown as a rating for each field.
