I updated to Version 6.0.28 just prior to making my last post. Is that the version you are referring to? Any other steps I need to take beside deactivate/activate and chmod 777?
FWIW, I've been using the following in my theme template for page.php but still experience this issue. At what point does your plugin update that database entry?
<?php echo do_shortcode('[wpgmza id="1"]'); ?>
