It’s not my place to comment here, but I think that both of your problems is all due to your sites using reCaptcha v2.0: where CF7 now apparently uses reCaptcha 3.0, ..

With the one at “seitenstopper.de/kontakt” asking to fill in a “I’m not a Robot [x]” click box, ..

‘The message could not be sent. Please confirm “I’m not a robot” and click on SEND again, or try again later. Or inform the administrator of the website.’

But there’s no box to tick.

My fix: I had to delete all of the version 2.0 plugins before I could get CF7 forms to send the contact mails correctly.

As I say: it’s not my place to comment, but what’s being reported here as an error with the plugin, (isn’t), but it’s also an issue that I went through before I got the forms to work properly. There’s also a lot of u-Tube vids out there on this issue.

Hope it helps.

I don’t have reCaptcha set.
I don’t have reCaptcha plugins installed for Contact Form 7.

This error appeared recently (WP 5.2?). Before that everything was fine. And my configuration didn’t change.

Solved for me!

I have a main website and a test website. Contact form 7 is installed on both websites and the keys of reCAPTCHA v3 are entered in both. And on both sides it ran smoothly the whole time. Now I have noticed that it does not work anymore and I get different errors, even though I made no changes. The ” I’m not a Robot [x] “click box” is actually nonsense, since I use reCAPTCHA v3.

After many other attempts this helped now: I have deleted the keys in contact form under integration. Then I deleted the websites with the keys in Google. Then I created new keys in Google and re-entered contact forms.

Now it works again as before.

Ok. I found source of my problem.
Looks like I can’t send any emails because there is a validation error: “Invalid mailbox syntax is used.”
Error appears because I use non-required [email] and one [hidden] field types in mailbox syntax.

This is wrong. I turned off CF7 required checkbox for [email] field because it doesn’t work properly across all browsers. And I use [hidden] field for a reason: my form is quite complicated.

Bottom line:
1) Validation errors in the backend shouldn’t prevent form from being sent. Or at least there should be option/hook/constant to turn that behavior off.
2) More detailed error messages are required so we developers can understand what the hell is going on.

It looks like fields shortcodes [email-1],[email-2] are removed from sender (“To:”) field. So, when form tries to send email it sends it to , address.

@panamta – I tested your form.

The red error border confirms that CF7 is not able to send an email from your site.

See If You Have Email Problems – most people that work carefully through this list of email sending issues are able to solve their particular problems.

There are a series of links to an article I wrote at the bottom of that page (which is recommended by the CF7 plugin author, though I’m not allowed to link directly to it here) that covers this topic in detail.

@detoris & @igortitarenko – see I have the same problem! Can I just reply to someone else’s post with “Me too”?.
