try this code:

<?php query_posts('cat=13'); ?>
<?php while (have_posts()) : the_post(); ?>

    <h3 id="post-<?php the_ID(); ?>">
      <a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a>
    </h3>
    <?php endwhile; else: ?>
    <p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
    <?php endif; ?>

oo, sorry..
it must be <?php echo get_post_meta(10,’Architect’,true) ?>

try this code:
<img src="<?php echo(get_bloginfo('url').'/comics/'.date('Y-m-d')'); ?>.gif">

your feed are not validated
https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fdarkshadowmx.net%2F%3Ffeed%3Drss2

author name in feed is strange: <ADMINNICENAME>

(3) <?php get_post_meta(10,'Architect',true); ?>

open 404.php file at your theme and replace code by the following:

<?php
header("HTTP/1.1 301 Moved Permanently");
header("Location: ".get_bloginfo('url'));
exit();
?>

Try this code

<?php /* If this is a category archive */ if (is_category()) { ?>
Archive for the category <?php single_cat_title(); ?>
<?php $cat = intval( get_query_var('cat') );
	if ( !empty($cat) && !(strtoupper($cat) == 'ALL') ) {?>
<img src="https://mydomain]/images/projects-icon-big-' . <?php echo $cat; ?> . '.gif" border="0" hspace="2" vspace="2" alt="' . <?php single_cat_title(); ?>. '" />
<?php } ?>
