After Developing a test App using Laravel 5.3, When I uploaded to the Cpanel it throwing Invalid exception Error. According to error message the App looking for some files from my local PC.Even after clearing all files from Storage\framwork\session it behaves alike previous.
App link: http://autocomplete.bappasarkar.info/
NB: After first time uploading the app threw an error
The only supported ciphers are AES-128-CBC and AES-256-CBC
Then I generate key by the artisan command
"php artisan key:generate"
After generating key when the App uploaded for the second time , it's throwing the current Error.
