Ratings: Half Stars and Custom Stars
The one that looks good (4.5 stars) is using 90 passed in, and the other is using 0 (the broken one).
I was leaving it blank on all my ratings, but I tried putting in a random number instead and everything seemed to work. The documentation says $rh->outputAverage($field, $value), but I don't know what $field is in the context.
I'll find a solution and post it here as soon as possible.
