Laravel 5.5 Backpack CRUD gives 404 Failed to Load Resource

Using Laravel 5.5, backpack installed, and the Jefferey Way's generators. Following the instructions on the site, but when I load the page in the admin pages, I am getting an error Failed to Load Resource. The crud is called presenter.

Instructions Followed:

    # STEP 1. create migration
php artisan make:migration:schema create_tags_table --model=0 --schema="name:string:unique"
php artisan migrate

# STEP 2. create a model, a request and a controller for the admin panel
php artisan backpack:crud tag #use singular, not plural

# STEP 3. add a route to routes/backpack/custom.php (under the admin prefix and auth middleware): 
php artisan backpack:base:add-custom-route "CRUD::resource('tag', 'TagCrudController');"

# STEP 4. add a sidebar item
php artisan backpack:base:add-sidebar-content "<li><a href=''><i class='fa fa-tag'></i> <span>Tags</span></a></li>"

What I'm seeing in the browser:

VM189:1 POST http://localhost/FroliconServer/public/admin/presenter/search? 404 (Not Found)

Trying to add/edit the crud from the page also gives an error 404 page not found.

Any clue as to what I've done wrong?
