Comments do not show for those who are not logged in
After updating the plugin to version 5.2.2 users who are no longer logged in can comment but cannot see comments
However on version 5.1.5 this is not an issue and users who are logged out can comment and see previous comments:
Is there any reason for this? We don't want to force our customers to sign in to view and comment but whilst this is broken we are forced to do this on one of our sites which is running the most up to date plugin.
Any help would be appreciated!
