Every time I try to approve a comment from main comments page (using single action link or selcting comments and selecting "Approve" from action menu, I get a white page of nothingness. The links for "approve" look suspiciously wrong, like:
edit-comments.php?s=&mode=detail&comment_status=all&pagegen_timestamp=2009-07-07+03%3A13%3A41&_total=5937&_per_page=20&_page=1&action=approve&doaction=Apply&_wpnonce=674abe9cbf&_wp_http_referer=%2Fwp-admin%2Fedit-comments.php&comment_type=all&delete_comments[]=69683&action2=-1
So far, the only way to approve is to edit a comment and change its status from the radio buttons.
