[Typo3-dev] $LANG is always NULL

[Brian Slezak]

I had the same thing you did, and posted about an empty admin panel. Screwy things happen when you try to use $LANG from the front-end. 

$LANG is a backend-only object.  You can't use it in the front-end.

It's not completely clear in the 'Inside Typo3' document, that this is speaking to Backend only.
http://typo3.org/documentation/document-library/doc_core_inside/How_to_acquire_label/

I can't find the documentation on it, but you need to use the following lines:

// This loads the locallang.php file located in EXT:ext_key/pi1/locallang.php
$this->pi_loadLL();

// Access labels through this function
$label = $this->pi_getLL('missing_').$check;

Example:
