found a dirt workaround:

phpList version 3.4.1
Edit the file /admin/languages.php
Lines 61 & 69 add $setlanguage = 'en';
Line 146 add $detectlan = 'en';

Code extract starting line 56

@session_start();

if (isset($_POST['setlanguage']) && !empty($_POST['setlanguage']) && is_array($LANGUAGES[$_POST['setlanguage']])) {
    //# just in case
    $setlanguage = preg_replace('/[^\w_-]+/', '', $_POST['setlanguage']);
//CMAK
    $setlanguage =  'en';
    $_SESSION['adminlanguage'] = array(
        'info'    => $setlanguage,
        'iso'     => $setlanguage,
        'charset' => $LANGUAGES[$setlanguage][1],
        'dir'     => $LANGUAGES[$setlanguage][4],
    );
    SetCookie ( 'preferredLanguage', $setlanguage,time()+31536000);
} elseif (empty($_SESSION['adminlanguage']) && isset($_COOKIE['preferredLanguage'])) {
    $setlanguage = preg_replace('/[^\w_-]+/', '', $_COOKIE['preferredLanguage']);
//CMAK
    $setlanguage =  'en';
    $_SESSION['adminlanguage'] = array(
        'info'    => $setlanguage,
        'iso'     => $setlanguage,
        'charset' => $LANGUAGES[$setlanguage][1],
        'dir'     => $LANGUAGES[$setlanguage][4],
    );
}

Next, the detectlan
