I have same problem as people said before.
Sonika says clear cookies but it will work only people who know that but common people can not do this.
I try lot of things.
Like change in sidebar.php & comments.php in
/public_html/wpress/wp-content/themes
whatever theme is…….to wp log out.
It does not solve my problem.
I think it is bug in WP or clear cookies some how.
Please reply me if anyone has solution.
