Removing "Archive" Heading.

I am having a lot of trouble trying to remove the word “Archives” from the top of the pages in my category menu. I am using Sugar and Spice theme. I have looked at the archives php and this is what is there:

<?php
/**
* The template for displaying Archive pages.
*
* Learn more: http://codex.wordpress.org/Template_Hierarchy
*
* @package Sugar & Spice
*/

get_header(); “page-title” ?>

<div id=”primary” class=”content-area”>

<?php if ( have_posts() ) : ?>

<header class=>
<h1 class=”page-header”>
<?php
if ( is_category () ) :
single_cat_title();

elseif ( is_tag() ) :
single_tag_title();

elseif ( is_author() ) :
/* Queue the first post, that way we know
* what author we’re dealing with (if that is the case).
*/
the_post();
printf( __( ‘Posts by %s’, ‘sugarspice’ ), ‘<span class=”vcard”>’ . get_the_author() . ‘</span>’ );
/* Since we called the_post() above, we need to
* rewind the loop back to the beginning that way
* we can run the loop properly, in full.
*/
rewind_posts();

elseif ( is_day() ) :
printf( __( ‘Day: %s’, ‘sugarspice’ ), ‘<span>’ . get_the_date() . ‘</span>’ );

elseif ( is_month() ) :
printf( __( ‘Month: %s’, ‘sugarspice’ ), ‘<span>’ . get_the_date( ‘F Y’ ) . ‘</span>’ );

elseif ( is_year() ) :
printf( __( ‘Year: %s’, ‘sugarspice’ ), ‘<span>’ . get_the_date( ‘Y’ ) . ‘</span>’ );

elseif ( is_tax( ‘post_format’, ‘post-format-aside’ ) ) :
_e( ‘Asides’, ‘sugarspice’ );

elseif ( is_tax( ‘post_format’, ‘post-format-image’ ) ) :
_e( ‘Images’, ‘sugarspice’);

elseif ( is_tax( ‘post_format’, ‘post-format-video’ ) ) :
_e( ‘Videos’, ‘sugarspice’ );

elseif ( is_tax( ‘post_format’, ‘post-format-quote’ ) ) :
_e( ‘Quotes’, ‘sugarspice’ );

elseif ( is_tax( ‘post_format’, ‘post-format-link’ ) ) :
_e( ‘Links’, ‘sugarspice’ );

else :
_e( ‘Archives’, ‘sugarspice’ );

endif;
?>
</h1>
<?php
// Show an optional term description.
$term_description = term_description();
if ( ! empty( $term_description ) ) :
printf( ‘<div class=”taxonomy-description”>%s</div>’, $term_description );
endif;
?>

</header><!– .page-header –>
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>

<?php

if ( $sugarspice[‘ap_layout’] == ‘excerpt’ ) {
get_template_part( ‘content’, ‘loop’ );
} else if ( $sugarspice[‘ap_layout’] == ‘firstfull’ ) {
get_template_part( ‘content’, ‘firstfull’ );
} else {
get_template_part( ‘content’ );
}

?>

<?php endwhile; ?>

<?php sugarspice_content_nav( ‘nav-below’ ); ?>

<?php else : ?>

<?php get_template_part( ‘no-results’, ‘archive’ ); ?>

<?php endif; ?>

</div><!– #primary –>

<?php get_sidebar(); ?>
<?php get_footer(); ?>

I have played around with it a bit and the only thing that makes any difference is removing <h1 class=”page-header”> but all this does is make the work smaller and move it to the side. I have taken out bits where it says archives but this has cause a fatal error in the site so I’ve always put them back. Any help would be appreciated. One of the pages that is affected is here:
