WordPress more-link

To remove 'more-link' try to add this code to your functions.php :

if ( ! function_exists( 'new_excerpt_more' ) ):

	function new_excerpt_more($more) {

		return '...';

	}

	add_filter('excerpt_more', 'new_excerpt_more');

endif;

And also in template the_excerpt(''); should be instead of the_content('');
