No date handler works on IONOS hosting

1

I’ve tried them all, none works. This is my current set up:

PHP 8.0
Kirby 3.9.6.1

Config:

return [
  'debug' => true,
 'date.handler' => 'intl',
  'locale' => [
   LC_CTYPE    => 'de_DE.utf-8'
 ],

  'panel' => [
    'css' => 'assets/custom-panel-css/custom.css'
],

];

template:

      <time class="date"><?= $article->date()->toDate('EEEE, MMMM d, YYYY') ?></time>

Error message:

Whoops\Exception\ErrorException thrown with message "strtotime(): We selected 'Europe/Berlin' for 'CEST/2.0/DST' instead"

If I outcomment the <time> ... </time> everything is fine, but I really would like to have that date thing.

Also, when I reload the page I sometimes get the date in Turkish (I guess) or English.

I put a php.ini on my webspace:

date. timezone = 'Europe/Berlin'

But that didn’t help.
IONOS seems to update their unix on their servers until sep. 15, but I can’t imagine, they let just break their clients websites. Speaking of clients and IONOS: :face_vomiting:

Without any date handler and locale + a clean install of the Kirby folder solved the problem.
