LARAVEL 5.4: PostTooLargeException in ValidatePostSize.php (line 24)

I am currently developing an app with Laravel 5.4. I am using xampp and changed the php.ini, php.ini-development and php.ini-production files with the following configurations

post_max_size = 100M

upload_max_filesize = 200M

memory_limit = 128M

I restarted Apache and my laravel development server but still, I get the error

Warning: POST Content-Length of 14253688 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

PostTooLargeException in ValidatePostSize.php (line 24)

I even restarted my PC and still not working. Am I missing something here?

Thanks
