I changed PHP version in Cpanel from 7.0 to 7.4 and after that reCAPTCHA displays properly, validates properly, but shows error "Please complete the anti-spam verification" when you click submit button on any form registration / question / comment.

Now I've made a teporary solution by changing PHP version back to 7.0 and reCAPTCHA works properly, but eventually I'd like to have PHP version 7.4. Any ideas?

Plugin: reCAPTCHA v2.0

Edit: I've made a few tests - I've changed PHP version to 5.4, 7.0 (native), 7.1, 7.4 and reCaptcha works correctly on my Q2A site only on PHP 7.0 (native).
Q2A version: 1.8.3

I've made some more tests.

Problem with reCAPTCHA appears ONLY if there's a code in site's files (for example in .htaccess file) that changes PHP version from native for our hosting to another. That's what we have in this case:
