I was wondering if anyone could lead me into the right direction with this. At one of my blogs, if you click on the author name, it goes to a 404 Error page/not found. I don't know if I messed something up in the Editor or if it was like that when I got the template, but I like how every thing is now except the 404.

How can I fix the problem? It would be okay to get rid of the link from the author name completely.

Where this link is appearing. Its usually in side bar.
Go to your admin panel, widgets, side bar and remove it.

No its not a widget. Its my author name after I write a post. I think some templetes have the author name linked and others don't. Mine links but goes to a 404 page.

Two options:

If you want the authors name linked - Fix the problem.

If you dont want the authors name linked - remove it.

Can you post a link?

By default, the hierarchy of WP is to result at your index template if no template is specified.

1st choice. author.php
2nd choice: archive.php
default: index.php

Therefore, the link itself must be coded wrong. Your author link is a function that should look like this:

the_author();

That will display the author name as a link.

Okay, I figured out how to delete it, but I kind of want to know how to fix it. I found that it is in the postInfo.php file and deleted the highlighted below:

<ul class="postInfo">
<li class="author"><span>Posted by</span>: <?php the_author_posts_link() ?> under <?php the_category(', ') ?></li>
<?php the_tags( '<li class="postTags"><span>Tags:</span> ', ', ', '</li>'); ?>
<?php edit_post_link('(edit this)', '<li class="editInfo">', '</li>'); ?>
</ul>

I still can't figure out how to fix it though. Any suggestions?

i think it has matter with your template.sometimes my blog has some mistake,my teacher alway ask me to change another template to have a try..
