New Language In Cal Module

Hi Community,

I’ve had installed the cal (calendar) module. I’ve translated all the words in the ‘new_lang’ folder to spanish and renamed to ‘es’.

In the main.php file in the config folder I’ve this configuration:

[b]return array(


'name'           => 'Redes Productivas',

    'language'       => 'es',

    'sourceLanguage' => 'es',


When I run the calendar it shows all the words in english, what am I doing wrong ? Thanks in advance.
