Lost traffic after upgrade


I’ve upgraded to pro and I’m seeing a sudden drop in traffic and my adsense revenue as well.
I was already using the firewall and blocking fake traffics but since I’ve lost adsense income, I think caching or some other settings are affecting my visitors.

Any suggestions please? Is there anything I can check?


I have now disabled couple of things and it looks like the traffic is coming back to normal.

Disabled Rocket Loader
Disabled Brotli
Disabled “Always Use HTTPS” (I don’t think this was the issue but I did anyway to test)
Disabled Web Application Firewall

Looks like there are still some issues.
Anyone know how I can rollback to Basic version?
I think somehow upgrading to pro broke the scripts in my website for some users because I got emails saying that they’re having script issues.

Many thanks
