Hello,
I've noticed a few problems with the comment voting system in v7.
First issue - The thumbs up and down hands do not stay highlighted after page reload. To clarify, they highlight once clicked, but are unhighlighted on page reload. So the user doesn't know if they voted previously. The "Highlight Voting Buttons for Voters" setting is on.
Second issue - There doesn't seem to be a limit on votes anymore. Users can up vote or down vote as many times as they'd like.
Neither of issues were present prior to updating to v7.
As of writing this, I am on version 7.0.2 and confirm that these issues are still happening.
I have also sent admin access to you guys via email.
Thank you,
-Chris
UPDATE:
For the people that are experiencing these issues and haven't seen it yet, @tomson wrote an awesome little tutorial on how to fix this. I can confirm that it has addressed these issues.
