Comments not possible for users with another mailadres than the owner

Hi Skandha, I have a comment section for messages. Now I have the problem that when I write a comment with my own e-mailadres, it works. When I write a comment with another mailadres, the comment doesn’t show up and it doesn’t show up in the overview of comments. I have the right configuration for comments. Can you please help with this problem? Kind regards Hans Hagmeijer
