Undefined property: Craft\WebApp::$request

Question

What could cause Craft to not define the request object?

I have a local site that recently stopped loading (front-end and back-end)

The error is happening in WebApp.php (line 630) when $this->request->getBrowserLanguages() method runs. The script fails because $this->request is not defined.

Other Craft installations work just fine. This site works just fine on a dev and live server with the same code. Any ideas on what I bumped?

Answer 1

This issue turned out to be caused by a config setting that had been added to general.php

'cacheMethod' => 'apc'

The server had APC installed but my local environment did not. There were a couple options to fix this:

1. Install Alternative PHP Cache (APC)
2. Setup a multi-environment config and override the cacheMethod setting with another method that is supported in your local environment, such as 'cacheMethod' => 'file'
3. Remove this line as it may not be needed anyway. apc is PHP byte caching and if your running PHP 5.5, that's enabled by default and apc is unnecessary

Answer 2

I had the same issue. But I was using memcache.

It turns out it was acually memcached which is a slightly different extension.

Enable the setting in the memcache.php config file with

'useMemcached' => true,
