reCAPTCHA validation never ok even with box ticked

[DESIGNfromWITHIN]

On my test page all seems to work until you try to send...
https://www.dswiss.com/de/kontakt-test/

Keep getting a error from reCAPTCHA, tried adding:
ini_set("allow_url_fopen", true);
But this did not work.

cURL for PHP is installed, the form works fine without the reCATCHA...

The form:
[[!FormIt? &hooks=recaptchav2,spam,email &emailTpl=contact_form_email_dswiss &emailSubject=Contact request ([[*context_key]]) from [[+name]] via DSWISS contact form &emailTo=[[*contact_form_email_to]] &customValidators=securesafe_contact_validator &validate=name:required:stripTags,firstname:required:stripTags,company:required:stripTags,email:email:required:stripTags,phone:required:stripTags &successMessage=

<script> $(document).ready(function(){ $.magnificPopup.open({ items: { src: '#succesModal', type: 'inline' } }); }); </script>

]] [[+placeholder]] [[!+fi.error_message:notempty=

[[!+fi.error_message]]

`]]

[[%securesafe.name? &topic=`contact`]] [[!+fi.error.name]]

[[%securesafe.firstname? &topic=`contact`]] [[!+fi.error.firstname]]

[[%securesafe.company? &topic=`contact`]] [[!+fi.error.company]]

[[%securesafe.email? &topic=`contact`]] [[!+fi.error.email]]

[[%securesafe.telephone_number? &topic=`contact`]] [[!+fi.error.phone]]

[[%securesafe.message? &topic=`contact`]] [[!+fi.error.message]] <textarea name="message" id="message" value="[[!+fi.message:htmlent]]" tabindex="7">[[!+fi.message:htmlent]]</textarea>

Line 991 mentioned in error log has this:

/** * Unset a placeholder value by key. * * @param string $key The key of the placeholder to unset. */ public function unsetPlaceholder($key) { if (is_string($key) && array_key_exists($key, $this->placeholders)) { unset($this->placeholders[$key]); } }
