Form submission breaks when enabling Cloudflare

Hi @cbrandt,

Thanks for your response :). I’ve completed your steps, but haven’t been able to resolve the issue yet. This is what I’ve done:

  1. Validated that the /wp-admin/admin-ajax.php gives a 524 error response and not a 403.
  2. Double-checked that there (logically) was no security event logged. This is indeed the case.
  3. Went through the documentation you provided and validated that the 524 issues were not due to a high server load or connectivity issues. I can validate this since the Form submits as expected as soon as I disable Cloudflare.

In addition to the steps above, I’ve also tried:

  1. Disabling the Captcha on the WPForm. This resulted in a 524.
  2. Added debugging to Wordpres by changing wp-config.php. This didn’t give any output, making me assume that the call was never routed to /wp-admin/admin-ajax.php.
  3. Validated that I have set Cloudflare SSL/TLS set to Full. (Not sure if that could impact it, but good to have the info anyway)

Do you have any other suggestions on how I might be able to debug this? I’ve tried all things that I could think of, but seem to be running a bit out of options :sweat_smile:
