Displaying the Chat on All Pages
Option 1 — Add to footer.php:
Add this line just before the </body> tag in your theme’s footer.php:
<?php echo do_shortcode('[pidixat]'); ?>
Option 2 — Use a WordPress hook in functions.php:

echo do_shortcode('[pidixat]');
}
add_action('wp_footer', 'add_pidixat_to_all_pages');
