php artisan migrate fails

[ghost]

Receiving the following error when running php artisan migrate:

`**************************************

• Application In Production!     *
  

---

Do you really wish to run this command? (yes/no) [no]:

yes

[ErrorException]
Undefined index: driver

`

Searching on the internet yielded no helpful results, I'm sadly not a developer.

Incorrectly modified database.php file, needs to remain as default.
