Google recaptcha not showing due to Cloudflare firewall rules (/wp-admin)

[user7058]

Hi Guys,

We have a Google recaptcha on the register page of our site. It is functioning properly.

After adding my site on cloudflare as well as adding firewall rules to block/challenge any access to (/wp-admin), I noticed that our Google recaptcha is not showing on our register page.

Here’s the Firewall rule we used: Tried both challenge & Block.
(http.request.uri.path contains “/wp-admin”) or (http.request.uri.path contains “/wp-login.php”) or (http.request.uri.path contains “/xmlrpc.php”)

After a few trials and error, it is confirmed that the block/challenge of “/wp-admin” is the main culprit. I noticed when I removed “/wp-admin”, the Google recaptcha will load.

How can I get the Google recaptcha to work while retaining the block of “/wp-admin” on cloudflare?

Please assist,

Regards
Lee

Good to know (seriously). I suspect that hard limits to wp-admin can cause problems, such as admin-ajax requests.

Are you seeing the event in the Firewall Log? There might be something in the request that you can add to the firewall rule as an exception.

Hi!

Ya your right, I’m seeing a lot of requests from admin-ajax. I’ve updated the Firewall rule:

(http.request.uri.path contains “/wp-admin” and not http.request.uri.path contains “wp-admin/admin-ajax.php”)
or (http.request.uri.path contains “/wp-login.php”)
or (http.request.uri.path contains “/xmlrpc.php”)

It seems to work now, hopefully I’m not missing anything.

Cheers!
