@laurentiu - no need, they need to update their backup manager extension.
@Eric535 - please download the extension from envato and upload it again in your app, just upload it through the web interface, it will fix this issue.

@twisted1919 What web interface? The backend?

Nevermind. I figured it out and it worked. Thanks
