Yes, I have both <?php wp_head(); ?> in header.php file and <?php wp_footer(); ?> in footer.php file. This is what I got back when I went to Chrome Dev Tools like you asked:
event.returnValue is deprecated. Please use the standard event.preventDefault() instead. jquery.js?ver=1.10.2:4

Does this mean there is a javascript error? (Like I said, basic knowledge of WordPress, almost no knowledge of js or php!) Thank you so much for your quick reply.
