Tag List Format

I recently upgraded to the newest version of WordPress and my Tags have seemed to have lost their list format. 🙁 I checked the coding on my the old WP version and this is what it is:

<li class=”tag_cloud”>
<h2>Tags</h2>

<? if ( function_exists(‘wp_tag_cloud’)){ ?>

<?php wp_tag_cloud(‘smallest=8&largest=8&number=600’); ?>
<? } ?>

<?php } ?>

</div>

It’s the same coding on the new WP. So I’m thinking I need to edit something, but I don’t know what, as I never touched this before.

So, anyhow, my tags are looking like this right now:

author story plot romance characters

I want them to look like a list:

author
story
plot
romance
characters

If anyone could help, I would appreciate it! If possible, please be a little thorough with me, especially on where to edit (what page, etc). I’m new to WP. Thanks!
