When Captcha is not filled out the form still can go through

It should not. The field should be validated and force the user to enter the captcha value.

Can you post a link to this form on a live site?

I am also facing same problem

Can you assist to resolve?

Thank You!

Hi, I am facing the problem. The captcha has been working fine for several months but just recently spam has been getting through.

A visitor can now send a message and not complete the maths question – the form still gets submitted.

I’ve deactivated and reactivated the plug in – no difference.

Ok, can you remove the double jquery code in your theme.

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.3.js"></script>

and fix this error:

Error: TypeError: $n(...) is not a function
Source: https://www.ennovationsols.com/wp-content/plugins/testimonial-slider/js/testimonial.js?ver=1.1
Line: 13

Then try again.

I also posted this same question two weeks ago at the dfactory site and never got a response. Is this even being resolved?

This is caused by an update of Contact Form 7

As stated in the 4.1 beta release, there has been a change in the user-input validation process and, if you use add-on plugins or custom code for Contact Form 7, you may need to modify the code to make it work with Contact Form 7 4.1.

Here is the solution:

                }
        }

The issue was with the $cf7_version = get_option(‘wpcf7’, ‘1.0.0’); in the file wp-content/plugins/wp-math-captcha/includes/integration-cf7.php

To solve the issue add “$cf7_version = $cf7_version[‘version’];” below ” $cf7_version = get_option(‘wpcf7’, ‘1.0.0’);”

or add the following code in your functions.php

add_filter('wpcf7_validate_mathcaptcha', 'my_mathcaptcha_validation_filter', 10, 2);

       function my_mathcaptcha_validation_filter($result, $tag)
       {
	       $tag = new WPCF7_Shortcode($tag);
	       $name = $tag->name;

	       if(!is_admin() && isset($_POST[$name]))
	       {
			$cf7_version = get_option('wpcf7', '1.0.0');
			$cf7_version = $cf7_version['version'];

		       if($_POST[$name] !== '')
		       {
			       $session_id = (isset($_POST[$name.'-sn']) && $_POST[$name.'-sn'] !== '' ? Math_Captcha()->cookie_session->session_ids['multi'][$_POST[$name.'-sn']] : '');

			       if($session_id !== '' && get_transient('cf7_'.$session_id) !== false)
			       {
				       if(strcmp(get_transient('cf7_'.$session_id), sha1(AUTH_KEY.$_POST[$name].$session_id, false)) !== 0)
				       {
					       if(version_compare($cf7_version, '4.1.0', '>='))
						       $result['reason'][$name] = wpcf7_get_message('wrong_mathcaptcha');
					       else
					       {
						       $result['valid'] = false;
						       $result->invalidate($tag, wpcf7_get_message('wrong_mathcaptcha'));
					       }
				       }
			       }
			       else
			       {
				       if(version_compare($cf7_version, '4.1.0', '>='))
					       $result->invalidate($tag, wpcf7_get_message('time_mathcaptcha'));
				       else
				       {
					       $result['valid'] = false;
					       $result['reason'][$name] = wpcf7_get_message('time_mathcaptcha');
				       }
			       }
		       }
		       else
		       {

				       $result->invalidate($tag, wpcf7_get_message('fill_mathcaptcha'));
			       }
		       }
	       }

	       return $result;
       }

Thanks guys, that seemed to have fixed it, although now I have an issue with:

“ERROR: captcha time expired”

upon clicking submit with the correct captcha value. Any ideas?
