Just uploaded version 2.0.7f to see if it fixed the display star error and its worse now. After you submit a comment it use to say "Thanks for posting a review" or something but now when you post a comment the comment box doesn't go away. The comment shows up but the box to type in the comment still shows up which it use to disappear since you shouldn't be able to post on the same product twice.
Also before you could go into virtuemart backend and open the review and hit apply to make it show the correct number of stars, but now when you do that it doesn't work.
It seems like the comment section has been forgotten about and hasn't been updated with new versions. It still is showing only 2 stars like the picture I posted even when you give it a 4 or 5 etc.
So if you can please test this on your own sites to see if I'm not the only one getting this bug.
