I just updated to 5.2 and am having a log of problems. I think that I got them all solved but this one is baffling me.

On auth/login and auth/register, I'm getting this:

RuntimeException in compiled.php line 7530: No supported encrypter found. The cipher and / or key length are invalid.

Now, I created a key on installation and it's in config/app.php. The cipher is the same as it was on installation, though: 'AES-256-CBC'.

Has anyone had this problem? How have you solved?

Try run this to generate a new key:

php artisan key:generate

And make sure that it uses that key

And put the new key here:

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

Or here:

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

I've made 2 new ones and put them in the latter.

I figured out out.

I wouldn't call that a proper solution. You should pull it from .env with env('APP_KEY') and use the first or both commands:

php artisan key:generate
php artisan config:cache

I did that and it didn't work, though. The only thing that's worked is the above link.

Thanks.

I am having that problem right now on forge. I've tried everything, it is even using the correct key:

at EncryptionServiceProvider->getEncrypterForKeyAndCipher('uLjED9Y87c9ks83mBGSK8hOWbRuuGhcxcnYCboq7s5w', 'AES-256-CBC') in EncryptionServiceProvider.php line 25

But it still throws the exception "No supported encrypter found. The cipher and / or key length are invalid."

It works on my local machine.

Thanks!

If you get this error, you've tried the above ./artisan commands and you are using apache, check the permissions on your .env file. need to be readable by the user/group that the webserver is running as. "chmod ugo+r .env" should resolve that issue.
