Problem with recaptcha v2

[elpustki]

Hello. I use WYSIWYG 14 and that is why I put recaptcha v2 on my pages.
The problem is that when the recaptcha is placed on the page, the message cannot be sent. When I delete it, you can send messages.
If anyone could look, the form is available at this address http://klifwdzydze.pl/rezerwacja.php

Maybe the PHP version on the server is out-of-date?

Ok, so what PHP version should I set on the hosting side? At the moment PHP5-PHP7 is set on the website side, while PHP 7.3 is set on the website hosting side (available versions are 5.2 5.3 5.4 5.5 5.6 7.0 7.1 7.2 7.3).

recaptcha v2 should work with PHP 7.3
Also, "allow_url_fopen" should be enabled on the server.

Everything worked. "allow_url_fopen" was the reason. Thank you very much for your help.
