Laravel 5.7 captcha validation strange issue

[dbulan]

I'm using Laravel 5.7 and PHP 7.2.4

My project have captcha on two pages: default page (where user can sign-in) and registration page.
In default page captcha validation works correctly, but in registration page validation always fails.

I spent a lot of time to find out what is going on.
My solution is:

1. open vendor/mews/captcha/src/Captcha.php
2. Find check($value) function, in my case line:428
3. Comment this line: //$this->session->remove('captcha');
4. Profit

I don't know why, but after that captcha works correctly in both pages.

i have this problem and i found the solution...when once you use captcha for example for login if you use captcha in another page session variable 'captcha' not clear and validation failed therefor i use

\Session::forget('captcha');

before load page that i used captcha in it.
