Hcapatcha's integration with Mailpoet outputs "Bad hCaptcha nonce!" errors

[ACCK-fabien]

Hello,

I have a problem with Hcapatcha's integration with Mailpoet. When I activate the integration for Mailpoet, everytime Hcaptcha seems to be used, there is a "Bad hCaptcha nonce!" error :

• When there is a form, there is no hcaptcha iframe and the form is locked
• When I want to access the Mailpoet forms in the back office the form is hidden and there is an error message
• When I want to access the list of my subscribers I can't see any. In this case, there is one error message that seams to appear for each time a refresh is done, so 2 messages every second, which results in lots of errors on the page

These errors were visible in another website I also work on so maybe it's a problem on Mailpoet's side ? I could contact them if needed. In the meantime, I deactivated hcaptcha on the website.

Thank you in advance, Fabien.

Just in case, here is the site's system info :

Hello Fabien,

Thank you for the report.

You have JS errors on the front end. Therefore, the hCaptcha cannot be initialized. To make it work, you need to fix the following bugs on the front end.

Issues reported in admin are valid; apologies. Fixed in v3.5.0, to be released next week.

Thanks ! Have a great day !
