I want to remove the "category:" header

hi everyone, i’m using wordpress on a local host and i want to remove the “Category:” part of the “Category: [category name]” that shows up on the top of category pages so it just show the name. For some reason, this same header is also showing up at of he top the archive pages instead of “Archive for: [date]” I’ve tried everything, even nullifing more than half of the archive.php and index.php code and nothing will get rid of it. Please help!

I’m assuming the problem is here somewhere:

<?php endif; ?>

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

        <div <?php post_class(array('pin-article', suevafree_template('span') )); ?> >

			<article class="article category">
				<?php if (is_tag()) : ?>

                    <p><?php _e( 'Tag','wip'); ?> : <strong> <?php echo get_query_var('tag');  ?> </strong> </p>

				<?php else : ?>

                    <p><?php _e( 'Category','wip'); ?> : <strong> <?php the_category(' '); ?> </strong> </p>

				<?php endif; ?>

but even when i cut out this section the header continues to appear. I’ve tried deleting it in the index.php and archive.php and both.

Any advice would be greatly appreciated!
