I use Revolution theme on WordPress 2.7.
The blog is set to allow anyone to post comments on articles. But after someone posts a comment, he sees only a blank page. Not the post page. This has been brought to my notice and I tested it. But it works ok when I am logged in as admin.
Though the commenter is taken to a blank page after posting a comment, the comment is saved.
I tried changing the theme to default theme from the latest WP pack (2.7). Still the same status. Hence I think it is not a theme-related issue.
Kindly provide me a solution to this nagging problem.
