This "fix" is for @Arnold (or whomever is lead dev for Directory) for the next version of Directory.
Currently when a user rates a listing, the stars change but the (0 votes; 0) information to the right side of the stars DO NOT change. This is due to the incorrect targeting of the class in the jQuery function in the file "directory/core/ratings.php" LINES 182 & 183
The Listing includes the POST ID in the ".all_votes" and ".all_avg" classes.
ie <div class="all_votes-1">0</div> and <div class="all_votes1">0</div>
To have the stats change along with stars, I changed the above to:
$(".all_votes-<? echo $post->ID; ?>").text(response.votes); $(".all_avg<? echo $post->ID; ?>").text(response.avg);
And it now works!
