use App\Aboutpages\About;
use Illuminate\Support\Facades\DB;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class AboutController extends Controller

use Illuminate\Database\Eloquent\Model;
use App\Services\Markdowner;

class About extends Model
{
    public $table = "about";
    public $fillable = ['title', 'content', 'user_id'];
}

About.blade.php -> view

@extends('frontend.layouts.app')

@section('content')

    <?php
      foreach ($about as $value){
        echo $value->content;
      }

Route::get('about', 'FrontendController@about')->name('about');
Route::get('about/index', 'About\AboutController@index')->name('about.index');

It says that the about variable is not available in the view. It does look like you are passing the variable from the controller, though. Is your web server working correctly? Do you test the default route?

A couple things though it may not fix your issue. First, why are you using the Query Builder and not Eloquent?

$about = App\Aboutpages\About::all();

Did you actually create the About model in an Aboutpages folder?

Secondly, your using blade templates so why are you using the php foreach loop directly. Use the Blade version.

@foreach ($about as $value)
    <p>{{ $value->content }}</p>
@endforeach

I found the mistake, the variable must be plural -> abouts not about in the Controller and the view.
