I've recently upgraded my blog to WordPress 2.1. I also upgraded Akismet to version 2.0. Both pieces of software have worked fine for some days, but I've just noticed a very upsetting behaviour in the backend: when I click on "Comments" option in order to manage comments, I get a blank page with a number (54, for example).
This behaviour also happened with WordPress previous versions, but it only involved the Akismet tab. In WordPress 2.1, Akismet tab is under the Comments management option. So, with the blank page I can't manage spam, nor approved comments.
On the other hand, I can see recent comments in the main Dashboard page.
