Answer 1

Did you enable error logging on your development machine?

Share your code which one is you're using with array_key_exists function.

Also share your current php version of development & server machine.

Answer 2

I had the same problem right now. I've received an error max_memory_limit, but because of nothing. In that case WAMP/LAMP/XAMP restart should help. Mye be helpful for somebody... :)

Answer 3

please enable $app->withEloquent(); in bootstrap/app.php . If you are using db, you must do this.
