The last several installs of the Integrated Video Tutorials I have added the code "define(‘WPMUDEV_VIDS_HIDE_SETTINGS’, true);"
To the wordpress wp-config.php file.
I placed it as the last item with the configuring settings. And when I check back in the WordPress Admin in Settings the 'WPMU DEV Videos' is still on the Settings menu.
And I did refresh the page.
This has happened on the past several installs of WordPress.
WordPress version is 3.5.1
Thanks for the feedback as to what might be wrong.
