Reply To: problems translate too

Sorry about the delay, I was working hard,

I am using version 3.3.1

The current languaje is defined in wp-config.php like that. Do you recommend me to change it?:

$browserlanguageis = substr($_SERVER[‘HTTP_ACCEPT_LANGUAGE’], 0, 2);
if ( $browserlanguageis == “en” || $browserlanguageis == “en_US”) {
define (‘WPLANG’, ‘en_EN’);
} else {
define (‘WPLANG’, ‘es_ES’);
}

The strings that are not being translated are supposed to be translated, like the labels of the admin dashboard, or some error fields of the form etc.
