Benevolence theme and tagline

Hi,

I am using the Benevolence theme as I am trying to set up a new design for my blog. I can’t let the tags show on top of my post. They are in the posts and I adapted the start of the post like this:

<?php _e("Filed under:"); ?> <?php the_category(',') ?> | <?php _e("Tags:"); ?> <?php the_tags(',') ?> </div>

The category is no problem but the tags stay empty.

Any advice?
