Captcha erro

Hi,

So I put a captcha at the end of my form, and I get the following message:

Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /htdocs/wp-content/plugins/liveforms/formfields/advanced/captcha.class.php on line 165

Warning: file_get_contents(https://mommysfitnesstime.com/?post_type=page&p=406&show_captcha=1): failed to open stream: no suitable wrapper could be found in /htdocs/wp-content/plugins/liveforms/formfields/advanced/captcha.class.php on line 165

Any idea what to do to fix it please?

Thank you!
