WP-PageNavi is outside my page instead of inside it.

Hello!

I installed WP-PageNavi by placing this <?php wp_pagenavi(); ?> inside the footer, as instructed in the plugin page. However, this places PageNavi underneath my footer, and to the left edge of the page (https://www.learnwriter.com/?s=templates&search=Search). As you can see this does not look too good. Would it make more sense to add the <?php wp_pagenavi(); ?> in the bottom of my index.php file, and my other pages files? Please help.
