PHP Fatal error – function add()

I also have the same error on two other sites (http and https)

The error is on that line:

$errors->add('captcha_error', "<strong>$error</strong>: $validate_result");

In this function :

// this function checks the captcha posted with registration
function si_captcha_register_post($errors) {
   global $si_captcha_dir, $si_captcha_dir_ns, $si_captcha_opt;

   $validate_result = $this->si_captcha_validate_code('reg', 'unlink');
   if($validate_result != 'valid') {
       $error = ($si_captcha_opt['si_captcha_error_error'] != '') ? $si_captcha_opt['si_captcha_error_error'] : __('ERROR', 'si-captcha');
       <strong>$errors->add('captcha_error', "<strong>$error</strong>: $validate_result");</strong>
       return $errors;
   }
   return($errors);
} // end function si_captcha_register_post

Hi !

I’ve never solved this issue on my sites.

I’ve built a new site and I still have issues with this plugin.

If the captcha field is empty or inaccurate I obtain the error :

Error thrown
Call to a member function add() on null

This time there is no PHP error thrown.
If I enter the right captcha everything works as expected.

HELP appreciated.

Regards

HI !

I use PHP 7.0.7

I’ll try to setup a new site and I’ll check step by step any changes to determine what’s going wrong.

Hi !

It still hang, but I don’t think it’s due to your plugin.

It seems to be the mix between your plugin and “WP-SpamSchield” and “New User Approve”.

“New User Approve” seems to be the mess maker.
