how to display the title of the category, when i'm in the category view

Hello,

when i’m in the category view of the wpdownloader, my title of the page is empty.

i tried this:

if ( ! function_exists( 'get_theme_page_title' ) ) :
		function get_theme_page_title() {
			global $post;
			$hide_title = esc_attr( get_post_meta( $post->ID, "hide_title", true ) );
			//$ptitle = stripslashes( esc_attr( get_post_meta( $post->ID, "ptitle", true ) ) );

			if ( empty($hide_title) ) :
				if( !empty($ptitle)) : ?>
					<h2 class="ptitle"><?php echo $ptitle; ?></h2><?php 
				$catname = get_category(get_query_var('cat'))->name;
				elseif (!empty($catname)) : ?>
					<h2 class="ptitle"><?php echo $catname; ?></h2><?php 	
				else : ?>
					<h2 class="ptitle"><?php the_title(); ?></h2><?php
				endif;
			endif;
		}
	endif;

But the title is still empty.

Can anybody help?

Thanks
