Go to the profiler’s main page, click the “Support” tab and search for [admin-ajax].
Do you see [access] => OK or an error instead?
I think the problem was, that enabling Cloudflare’s “Development mode” is not the same as disabling the proxy by making the clouds grey 😉
Thanks, now it’s working
You can try to bypass your CDN by directly accessing the site via its IP address and adding the host field:
1. In the “Page to profile”, select “Custom post/URL” and enter the server real IP address instead of the domain. For instance: https://1.2.3.4/some-page-to-profile/
2. Then click the “Advanced Options” button and in the “HTTP headers” section, enter the “Host” field with your domain name. For instance: Host: example.com
If you block IP addresses that don’t originate from the CDN at your server level, that won’t work.
Thanks for providing this workaround. Disabling the CDN for a test is not a problem.
If I need to test more it’s always better to test via the staging environment.
