Missing/not reachable link in columns text

I fixed it on my own (without any knowledge in PHP, haha): With help of Google and the child theme tutorial given here I managed to find, analyze and override the function nirvana_singlecolumn_output($data) in widgets.php in my child project (functions.php). I added/changed

<?php echo '<a href="'.$link.'" '.$blank.'>'; ?>
<?php the_excerpt_max_charlength(do_shortcode($text), 90); ?>
<?php echo '</a>'; ?>

and a function which shortens the excerpt text of each random post (with a different char amount from that Nirvana uses).

function the_excerpt_max_charlength($text, $charlength) {
	$excerpt = $text;
	$charlength++;

	if ( mb_strlen( $excerpt ) > $charlength ) {
		$subex = mb_substr( $excerpt, 0, $charlength - 5 );
		$exwords = explode( ' ', $subex );
		$excut = - ( mb_strlen( $exwords[ count( $exwords ) - 1 ] ) );
		if ( $excut < 0 ) {
			echo mb_substr( $subex, 0, $excut );
		} else {
			echo $subex;
		}
		echo '...';
	} else {
		echo $excerpt;
	}
}
