OK, thanks. I just checked the default theme what command is used there to make it work, and assumed that it used what we’re supposed to use. 🙂
Make sure you have the line
<?php do_action(‘wp_footer’); ?>
in the footer of the themes.
Check your theme that it contains the line
<?php do_action(‘wp_footer’); ?>
in the footer. Maybe as the last line, before closing the body and html-tags.
