追記いたします！ @ragner_k さんから、web.phpファイルを確認したいとのことなので下記に記載します。
お手数おかけしますがご確認お願いいたします。

*/
Route::get('/', function () {
return view('welcome');
});
Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');
Route::resource('posts', 'PostController', ['only' => ['index','show', 'create', 'store']]);
Route::get('posts/edit/{id}', 'PostController@edit');
Route::post('posts/edit', 'PostController@update');
Route::post('posts/delete/{id}', 'PostController@destroy');
また、足りない情報やご指摘があればお願いいたします。
よろしくお願いいたします！
