I dont know if this just my blog, but today I was checking the spam list. I went to page 2 and then page 1, and I got a mysql error:
WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-50, 0' at line 1]
SELECT * FROM wp_comments WHERE comment_approved = 'spam' ORDER BY comment_date DESC LIMIT -50, 0
It loads up this url when I go to previous page:
<<my blog>>/wp-admin/edit-comments.php?page=akismet-admin&apage=
It doesnt include page=1 when I press previous page.
Is it me, or is this a bug?
