Custom Sidebars - Not Working After Upgrade

I have a WP site (not a multisite) that uses a few WPMUDEV plugins. This site is not listed in my wpmudev account. I updated several plugins today. The only plugins that are not working are the WPMUDEV plugins (Custom Sidebars and Popup). I had to delete these and downgrade to the prior version. Is there something that recently changed which I should be aware of when using these plugins on standalone sites, or sites that aren't listed in my account here on wpmudev.org?

Thanks,
Chris
