When does the issue occur?
I have installed https://github.com/bubasuma/yii2-simplechat extension. After extending their classes i got this issue. I am using twig as the template engine.

I use this command to install the twig.

"require": {
"yiisoft/yii2-twig": "> 2.0.4",
"bower-asset/twig.js" : "0.8.4@stable"
},
After run the composer :
I write the code in config/web.php

    'view' => [
        'renderers' => [
            'twig' => [
                'class' => 'yii\twig\ViewRenderer',
                // set cachePath to false in order to disable template caching
                'cachePath' => false, //'@runtime/Twig/cache',
                // Array of twig options:
                'options' => [
                    'auto_reload' => true,
                ],
                // add Yii helpers or widgets here
                'globals' => [
                    'html' => '\yii\helpers\Html',
                ]
            ]
        ]
    ],

It show the twig layout file code on browser.

Try Twig 2.2.0 and don't specify bower-asset/twig.js
