Not working on user and content listing pages

1) On the user listing page at Home › Administer › User management, the status AJAX links do not work. When I click on "active", it gives me the error "toggling the setting failed". I am using the admin account.

2) On the content listing page at Home › Administer › Content management, content table has a "status" column, but the values on that column "published" and "not published" are not clickable. They are shown as text. They are not links.
