I'm unable to load the plugin's locale file (.mo). I did all the procedues described in the http://codex.wordpress.org/Writing_a_Plugin but its not working. If I the lang string to the wordpress default wp-content/language/de_De.mo
file then its show the correct translated string. but not loading the data from my plugin folder :(
EDIT:
$plugin_dir = basename(dirname(__FILE__)) ."/lang/";
load_plugin_textdomain( 'tboy_displayTimeZone', null, $plugin_dir );
