[WPMU DEV Dashboard] 403 error messages

Hi there,

My website isn’t working since yesterday and after messaging my hosting provider they have told me that due to your plug in the website has gone down .
Because these resources can’t be loaded, your website isn’t loading correctly.

This is what they said
“I’ve had a look at your website, and there’s a lot of 403 error messages when loading resources from “hb.wpmucdn.com”, which appears to be this provider: https://premium.wpmudev.org/cdn/
Do you (or your developer) have an account with that provider (https://premium.wpmudev.org/cdn/)? If so (or you’re not sure), you will need to contact them and find out why you’re getting these errors.”

Hope this issue can be fixed
