GDragon, dude...first off, be a little more of a SUPPORT for the issue for crying out! Secondly, this is a great plug-in that I myself am utilizing on my site. I used to have this same issue, myself, and there are ways of testing in different browsers without actually having a MAC based computer.
However, 90% of component errors are usually made by the user, but in this case, it may only be because of the lack of enough rated posts/pages to display any data. Try adjusting the data and Save to account for like you said, a 'minimal' amount of posts/pages VOTES to say, '1' in order to utilize the widget.
I'm having a heck of a time using the GDragon forum site...primarily your search function. I'm trying to do a search for a topic and no matter how many words or characters I enter...I ALWAYS get back the same message:
The following words in your search query were ignored because they are too common words
I suggest this be looked into to properly make the forum functional, otherwise, users have to weed through hundreds of posts for the information they're looking for, which almost completely defeats the purpose. Thanks!
