I have created a contact form in the Page Builder Pro 5.4.4 (latest Helix Ultimate-Template) and am using the classic math puzzle as a spam protection measure. The form works without any issues, and emails are successfully received through it.
However, the volume of spam has increased significantly in recent times. To address this, I installed the "Friendly Captcha" plugin in my Joomla 5 installation and set it as the default captcha in Joomla's settings. This integration works seamlessly within Joomla itself and adheres to GDPR requirements.
I can also select this captcha as the spam protection method in the Page Builder’s contact form. Unfortunately, when I fill out and attempt to submit the form, nothing happens: no email is sent, and the form simply resets.
Since this is a captcha integrated with Joomla, there seems to be a standard interface in place that allows all captchas to function properly if they adhere to it. Therefore, it should be possible for Joomla captchas—regardless of the type—to work within the Page Builder.
How can this issue be resolved? What additional information would be helpful to narrow down the problem?
