Author Template Problem

Hello everyone.

I’m using author template (author.php) for display each author posts. I’m using query_posts("&cat=-5"); code snippet for exclude a category.

But if i use this snippet author template isn’t working. So it’s displaying all author with own posts (in example: http://www.sinemalardan.com/author/admin/ -it’s will be display other author’s post).

My blog is here: http://www.sinemalardan.com

Thanks.
