i have problem in session i don't know what it is

It sounds like your session timed out. Like the session time is 2 hours and you left the browser open for 2+ hours and then came back and submitted something. So it sent the expired csrf token, which mismatched.

@CRONIX - not 2 hours sometimes only minute

We would need more info on the setup, like what the view has in regards to crsf token field, what the actual controller has in terms of handling this etc.

every page has this code in its form

<input type="hidden" value="{{ csrf_token() }}" name="_token">

I made this middleware

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;
use App\keywords_model;
use App\category_model;

class IsUserAdmin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if (Auth::user()->admin !=1) {
            $allKey = keywords_model::orderby('id','desc')->get();
            $categories = category_model::where('parent_id','=','0')->orderby('id','asc')->skip(0)->take(5)->get();
            return redirect('login', compact('allKey','categories'));
        }
        return $next($request);
    }
}

I made now log in and went to control panel and viewed all packages and insert one ok inserted and route me to all packages after that tried to add another package I get this error

Whoops, looks like something went wrong.

Have you checked this out? https://laravel.com/docs/5.7/csrf#csrf-x-csrf-token

table migration for users

Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->integer('admin');
            $table->rememberToken();
            $table->timestamps();
        });

Have you tried in your CMD below commands

php artisan cache:clear
php artisan view:clear
php artisan route:clear

Can you show controller function as well, and have you used as like below in top of your controller function.

public function __construct()

    {
    $this->middleware('auth');  
    }

@MUNAZZIL - I make this all every time I found the problem but it is not good

php artisan optimize
php artisan cache:clear
php artisan config:clear
php artisan view:clear
php artisan route:clear

@TIVOSOHO - I use laravel 5.2

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;

use App\package_model;
use App\keywords_model;
use App\category_model;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $umra = package_model::where('package_type','=','3')->orderby('id','desc')->skip(0)->take(6)->get();

        $last_tour = package_model::where('package_type','=','5')
                                    ->where('package_type','=','9')
                                    ->orderby('id','desc')->skip(0)->take(1)->get();
        $last_tours = package_model::where('package_type','=','6')
                                    ->where('package_type','=','7')
                                    ->where('package_type','=','8')
                                    ->where('package_type','=','10')
                                    ->where('package_type','=','11')
                                    ->where('package_type','=','12')
                                    ->orderby('id','desc')->skip(0)->take(4)->get();

        $all_package = package_model::orderby('id','desc')->skip(0)->take(15)->get();
        $allKey = keywords_model::orderby('id','desc')->get();
        $categories = category_model::where('parent_id','=','0')->orderby('id','asc')->skip(0)->take(5)->get();

        return view('home', compact('umra','last_tour','last_tours','all_package','allKey','categories'));
    }
}
