Q:

Wordpress Categories and Tags not linking

I am not sure why this issue has risen up, never had this problem in any of my other blogs that I have done. But perhaps someone is able to shed some light on this.
I have a list of posts.
TITLE | CATEGORIES | DATE
The title links correctly, But the CATEGORIES do not. My Code for displaying the category is:
<li class="category"><?php the_category(', ') ?></li>

When I click the category link it displays 404 not found but there is a URL issue that comes in:
http://domain.com/categoryName
SHOULD BE
http://domain.com/category/categoryName
I do have the exact same issue with the TAGS but I don't know what to reference for the TAG feature.
I used the Default Widget for "most popular tags" and it just doesn't link properly no matter what... and it too has the url of:
http://domain.com/tagName
Any help would be appreciated.

A:

Sorry about this post, it was an issue with the previous theme-author.
He removed the the code for the categories.
