Not Working with Divi Theme

Was working fine about 1 month ago but now their visual builder doesn’t work.

Any insight into this? Divi will just tell me to use another performance plugin I imagine.

I also get this message when running a performance test which I never used to get:

The performance test didn’t return any results. This probably means you’re on a local website (which we can’t scan) or something went wrong trying to access WPMU DEV. Try again and if this error continues to appear please open a ticket with our support heroes
