Contact Author not working in IE

I added an author info box to my theme. It’s working fine in every browser I tested it in except Internet Explorer (version 7). The problem is the “contact the author” link isn’t working. It just shows as text.

Here’s a link for an example: https://www.theinnocentabroad.com/five-free-things-to-do-in-melbourne/

and the code I used and modified to write the author info box: ` <?php if (get_option(‘woo_author’) == “true”) { ?>
<div class=”author-description”>
<div class=”ThisPostBy”> This Post By</div><?php echo get_avatar( get_the_author_email(), ‘100’); ?><?php the_author_posts_link(); ?> – <?php _e(‘who has written’,woothemes); ?> <?php the_author_posts(); ?> <?php _e(‘posts on’,woothemes); ?> /”><?php bloginfo(‘name’); ?>.
<p><?php the_author_description(); ?></p><div class=”contactto”“><?php _e(‘Contact the author’,woothemes); ?></div><br style=”clear:both;” />
</div>`
