reCaptcha V2 is not validating

Hello Jeroen,

I contacted our provider and received the following helpful response.
---
About a week ago, attacks originated from the IP address 185.41.124.157, for example, on xmlrpc.php.
Therefore, it ended up on blacklists and was blocked by our data center.
Since there have been no new anomalies in the last few days, this has since been lifted.
---

So the IP was indeed blocked by our provider.
The reason for the block is understandable and more than reasonable.
This risk of being affected without fault always exists, at least when a hosting package doesn't include a truly individual IP address.

I'm glad the situation has now been clarified.
I assume that other providers, possibly including Google, have also implemented similar blocking measures and have since lifted them.

Conclusion:

If your server IP is blocked in the future, you can always perform the update manually.

Best regards, Ingmar

Hello Jeroen,

We've made changes to the ReCaptcha code.
We'd like to deploy and test the changes on your production site.
This is necessary because the ReCaptcha code works perfectly everywhere else, even on our local copy of your site.

Can we use the FTP access provided to upload a new version of the following file and use it to test ReCaptcha on the frontend?

components/com_visforms/src/Recaptcha/Recaptcha.php

Best regards, Ingmar

Hello Ingmar,

Thank you for the update and the work you put in! I will inform our provider on this. The reCaptcha from Google is not (yet) working. I switched to an alternative for now.

Hello Jeroen,

you are welcome.
We're also gaining valuable experience working with and using Visforms.

It's good that you're using an alternative temporarily.

My question in the last post was whether we could have a form with Recaptcha on your site for testing.
And whether we could use the FTP access provided to share a Recaptcha file on your server.

We have modified the code for Recaptcha and want to test whether it works for you with the changes.
This is necessary because the Recaptcha code works perfectly everywhere else, even on our local copy of your site.

Best regards, Ingmar

Hello Ingmar,

You can use the following form for testing:
scoutingalphen.nl/meer-informatie/contact-redactie
The ID of this form is 5.
Let me know if I can do anything more for you.

Hello Jeroen,

With your FTP access and the test form, we were able to get Recaptcha V2 working for you as well.
You don't need to do anything else on your server, and in particular, you don't need to apply the hot-fix below.

You're already running the fixed version.
The hotfix is ​​included in this post is for all other users who might be affected.

The fact that the original Visforms implementation didn't work for you is definitely due to Google unexpectedly blocking the dedicated request with 'CUrl'.

But now the modified Visforms implementation works for you as well and has become more stable.
Thank you for your patience and cooperation.

There is a hotfix to resolve the error for:
Joomla 5 and the current Visforms version 5.3.1

Please back up the old file first in case unexpected problems arise.

Download the following file:
- vi-solutions.de/forum-bugfixes/Recaptcha.php_5.3.1.txt
Rename the downloaded file to
- Recaptcha.php
Using the downloaded and renamed file, overwrite the following file on the server:
- components/com_visforms/src/Recaptcha/Recaptcha.php

Kind regards, Ingmar
