I created a blog using Drupal 7. Admin can add and display comments correctly. But when an anonymous user adds comment, then this was not shown in the unapproved list and the blog page shows error. Already approved comments will be shown in the approved list. But newly unapproved comments from anonymous user won't display. If I delete the unapproved comments from database the blog page works fine. I gave permission to anonymous user to post comments. Anyone please help me.
