Author page Not Found
Problem: Clicking on the author name link (Ex.: http://www.leonardowood.com/author/Leonardo%20Wood/) in posts shows Page Not Found.
Solution:
The author link is supposed to be http://www.leonardowood.com/author/leonardo-wood/
Add the following to your theme's functions.php, reload your site twice.
global $wpdb;
$wpdb->query("UPDATE `{$wpdb->users}` SET `user_nicename`='leonardo-wood' WHERE `ID`='1'");
In the above replace "leonardo-wood" with your user nicename (User name in small case with hypens between spaces).
The above also assumes that ID of user in question is 1. This can be checked via phpMyAdmin in wp_users table.
After ensuring that this has been fixed, remove the above code from functions.php.

Requirement: Only posts from a certain category should appear on Posts page
How to: Edit your theme's index.php.
Ex.: Change
<?php if ( have_posts() ) : ?> <?php while ( have_posts() ) : // The Loop ?> <?php the_post(); ?>
to
<?php if ( have_posts() ) : ?>
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; query_posts("cat=1&paged=$paged"); ?>
<?php while ( have_posts() ) : // The Loop ?>
<?php the_post(); ?>
In the above, change "1" to the ID of category from which posts should be shown. Posts from all other categories won't appear.
Category ID can be seen by going to Posts -> Categories, placing the mouse cursor on desired category and observing the number at the end of URL in the browser status bar.
