Broken in WordPress 4.8?

Same issue here. After updating to 4.8 – from version 4.7 – the plugin stopped sending emails, remaining locked on the loading arrow. I searched online and the only option I found (and that actually works) is a downgrade to 4.7.
I’m using DIVI theme 3.0.64 + Worpress 4.8.
What’s wrong? Help me.

The same after updating to 4.8. I had to revert to 4.7.

Did you deactivate REST-API for anonymous user? Since CF7 4.8 there is a fault in the plug. I have asked several times if there will be any solution to fix that bug, but no support.

I just updated to 4.8.1 but the problem remains. Can’t send message.

Same here. Updated today to 4.8.1 but the problem is still there.
If there is no solution, does anyone have any idea where the problem is?
