If 'member_dashbiard' is your route name:

no that's from resource/view/member_dashboard.blade.php ,sorry i forget the route code :

Route::match(['get', 'post'], '/spt_dashboard', '\App\Http\Controllers\AdminSptController@cbInit');

Route::match(['get', 'post'], '/spt_dashboard', '\App\Http\Controllers\AdminSptController@cbInit')->name('spt.dashboard');

...

<li><a href="{{ route('spt.dashboard') }}">Buat SPT</a></li>

i've done change that code

<li><a href="{{ URL::asset('spt_dashboard')}}">Buat SPT</a></li>

then the output is white screen

when im follow your suggest, i got error here :

(1/1) FatalErrorException Method Illuminate\View\View::__toString() must not throw an exception, caught ErrorException: Route [spt.dashboard] not defined. (View: C:\xampp\htdocs\crud\vendor\crocodicstudio\crudbooster\src\views\header.blade.php) (View: C:\xampp\htdocs\crud\vendor\crocodicstudio\crudbooster\src\views\header.blade.php) (View: C:\xampp\htdocs\crud\vendor\crocodicstudio\crudbooster\src\views\header.blade.php)
