this problem solve by under code to app/Http/Middleware/VerifyCsrfToken.php

class VerifyCsrfToken extends BaseVerifier
{
/**
 * The URIs that should be excluded from CSRF verification.
 *
 * @var array
 */
protected $except = [
    'elfinder/ckeditor',
];
public function handle($request, Closure $next)
{
    $regex = '#' . implode('|', $this->except) . '#';

    if ($this->isReading($request) || $this->tokensMatch($request) || preg_match($regex, $request->path()))
    {
        return $this->addCookieToResponse($request, $next($request));
    }

    throw new TokenMismatchException;
}
}
