Hi everyone,
I had a site that was calling the shortcode in header.php and after the WP update I saw the same error as pwit up above. I reverted to the previous version of the Kimli Flash Player plugin, available here, by recommendation of the plugin author from another post. I’m referring to his last reply in the thread.
Then, if you have automatic updates on your site, you’ll have to edit the kml_flashembed.php file so that it says Version: 2.5.1 to prevent auto-updating and breaking the site again.
Hopefully this helps some people.
