'BadMethodCallException' with message 'Method after does not exist.'

Hi,

I am getting the following error in my app after upgrading to laravel 5.2 from 5.1: NOTE: The error occurs under my Ubuntu Server 14.04 and the code is deployed using deploybot connected to a github account. The error does not occur on my Windows development machine.

[2016-01-01 20:08:58] local.ERROR: exception 'BadMethodCallException' with message 'Method after does not exist.' in /usr/share/nginx/my_server_path/vendor/laravel/framework/src/Illuminate/Support/Traits/Macroable.php:81

I am quite new to laravel and this is fairly fresh application.

Here's my composer:

    ]
},
"config": {

Any ideas?
