@bvdputte That doesn’t make sense for a single language website, though.
@jonathanhess I just checked the locale setting in config. There used to be a bug but it was supposed to be fixed.
Hm… I’ll check myself.
Edit: setting the locale in config.php works for me in a 3.1.0 Starterkit.
<?php
return [
'debug' => true,
'date.handler' => 'strftime',
'locale' => 'de_DE.UTF-8',
];
