hi guys please help i am new in laravel 5.3.16 Class 'session' not found

Is there somewhere in your code you call class session (all in lowercase)

no there is no place i have introduced the class session on my code

I'm not sure about this, I think those files with big names are cached views in storage\framework\views. So check your views.

i have seen the file and the error then after disabling this part of code

@section('title')
    Enterprenuer Base

@section('content')

        <div class="col-md-6">

Clear view cache: php artisan view:clear

if you're trying to include the csrf token, you do that like this:

{{ csrf_field() }}

<!--input type="hidden" name="_token" value="{{ session::token() }}"-->

after disabling that part of the code the systling have disappeared

@ willvincent i have cleared the caches but nothing changes

@jonimwangi45@gmail.com Use php comment (<?php /* */ ?>) or blade comment. Or just remove that line from your code.

If your intention is to include csrf token, use {{ csrf_field() }} as @willvincent said.

*/
//use class Session;

Route::get('/', function () {
    return view('welcome');
})->name('home');

Route::post('/signup', [
    'uses' => 'UserController@postSignUp',
    'as' => 'signup'
]);

this is my app\Http\Controllers\UserController.php

<?php
namespace App\Http\Controllers;
//namespace routes;

use Illuminate\Http\Request;

class UserController extends Controller
{
    public fuction postSignUp(Request $request)
    {
        $email=$request['email'];
        $first_name=$request['first_name'];
        $password=bcrypt($request['password']);

        $User=new User();
        $User->email=$email;
        $User->first_name=$first_name;
        $User->password=$password;

        $User->save();

        return redirect()->back();


    }
    public fuction postSignIn(Request $request)
    {

    }
}

just repair in this syntacs like my code

@if(Session::has('message')) {{ Session::get('message') }} @endif

'Session', not 'session'
