Just open terminal go to your project and type "php artisan key:generate".

@kunalcoder23 I have done that but the error still occur please you can join the conversation here http://stackoverflow.com/questions/37505809/no-supported-encrypter-found-issue?noredirect=1#

what are you doing man seriously

'key' => env('o/tPhyhKmuLoJMWXZeV8b10OFoCT62z6WKuC3HO5Jbw='),

'cipher' => 'AES-128-CBC',//'AES-256-CBC',

what is this ?

It should be

'key' => env('APP_KEY'),

'cipher' => 'AES-128-CBC',//'AES-256-CBC',

@kunalcoder23 Solved it

'key' => '9TSL9BsEjZyoM9BjX9du0XaLnCDi4m4Z',// env('9TSL9BsEjZyoM9BjX9du0XaLnCDi4m4Z'),

'cipher' => 'AES-256-CBC',

php artisan config:cache

Did the magic.

Do it is the direct method man but it is the wrong completely wrong way. Please think coding as a religion and follow it man.

lol kunalcoder23 is right though

you're doing it all wrong
