Compromising Captcha and Google ADS


#1

Our custom theme WordPress site which uses Google ADS, gets after migration to Cloudflare either following Captcha or no Google ADS at all, depending of the browser.

JavaScript console outputs :

  1. Chrome MAC OS X Captcha, no Google ADS, :
    Cross-Origin Read Blocking (CORB) blocked cross-origin response
    [studio.sdk] Using default ad parameters in test

  2. Chrome Windows : no Captcha, no Google ADS
    Get http://…/adsbygoogle is 0

Default Cloudflare WAF rules, turning WAF ( challenge ) off or pausing the site does not solve the problem.
Thanks

Sorry, Chrome Windows AD blocker was active.
There is no difference in Chrome Windows / Mac behaviour, only single Captcha problem that follows:

Chrome no AD blocker:

compromising Captcha, no Google ADS, Java Script error:
Cross-Origin Read Blocking (CORB) blocked cross-origin response
[studio.sdk] Using default ad parameters in test

Safari, Opera, Internet Explorer : Google Ads Ok
