Oh, thank you so much for helping out. I'm sorry for being an inconvenience. I must say I ran into a 'No application key' problem, but I fixed that with
php artisan key:generate.

@rahul, oh no. I used the second step:

@rahul What do you mean by "new build" ? You mean the .zip file?

Doesn't work for me either.

I used the CLI method. Well, it didnt work. Again. And I'm already behind schedule on my presentation. Could it be something is missing from my PC's XAMPP installation? Something overlooked, perhaps (though from the nature of the error I doubt that! )?Screenshot (1).png

So I suppose both GUI installation and CLI installation have been fixed, and that I can use any of them?

UPDATE ON CLI INSTALLATION:

It gets stuck at Migrate and Seed for a long eime, then gives this error:

Class Webkul\Core\Repositories\SliderRepository does not exist
Previous exceptions
Declaration of Webkul\Core\Eloquent\Repository::count() should be compatible with Prettus\Repository\Eloquent\BaseRepository::count(array $where = Array, $columns = '*') (0)

I can't seem to find the file where I can change type from json to text

THIS IS THE ERROR THAT BOTHERS ME.
