In order for the WP Bounce to function properly your theme footer.php must have this tag:
<?php wp_footer(); ?>
This tag is very important for the wordpress site. All themes must have it in their footer.php just before the closing </body> tag or else it breaks many plugins.
How To Fix
- In your wordpress admin panel go to Appearance -> Editor and click on footer.php in the list of files on the right.
- Find </body> tag and right before it copy and paste this:
<?php wp_footer(); ?>
Note: Backup your files before making this change. If you have any firewall plugins disable them before making changes.
