Question

I am building a project using Laravel. It was working fine on localhost, but when I upload it to the server (the server has comodo ssl installed), I receive the following error:

RuntimeException in EncryptionServiceProvider.php line 29:

Can anyone help solve this error?

Answer 1

Add "illuminate/html": "~5.0" to require section of your composer.json file. Just like this:

...
"require": {
    ...
    "illuminate/html": "~5.0"
    ...
},
...

Then run composer install command. When composer install gets complete. run php artisan key:generate. You will get a message like this:

Application key [get 32 char key] set successfully.

Answer 2

if you are using app.php configuration file instead of reading key from .env file, then you can remove the env() function on key variable, ex:

'key' = env('someRandom36CharsString'),

to

'key' = 'someRandom36CharsString',

Answer 3

You only type in console:

php artisan key:generate

And if your app.php not change this Key, change manually.

Next if you should then happen to get this error message:

[ErrorException]
file_get_contents(/path/to/my/project/.env): failed to open stream: No such file or directory

Then make a copy of the .env.example file and try again:

cp .env.example .env
php artisan key:generate

Answer 4

write in console php artisan key:generate

you will get message like: Application key [get 32 char key] set successfully.

replace app key in config/app.php like 'key' => env('APP_KEY', 'insert get 32 char key'),//line number 81

Answer 5

solved with:

php artisan key:generate

Answer 6

Please make sure you have this requirements in your machine.

1. PHP >= 5.6.4
2. OpenSSL PHP Extension
3. PDO PHP Extension
4. Mbstring PHP Extension
5. Tokenizer PHP Extension
6. XML PHP Extension

Then after install or updating your project by

composer update

After this you have--

.env.example

Make a duplicate and rename it to--

.env

and make changes according to your database configuration or any other modifications you need.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your db name
DB_USERNAME=username if any otherwise root
DB_PASSWORD= your password if not set leave blank

Finally generate your application key by--

php artisan key:generate

For Someone may be only last step is enough. But I have this problem every time I clone any laravel project. This whole step makes this with any hazard.
