I just downloaded the latest version and encountered this error:

[b]Fatal error:  Uncaught Error: Call to undefined function CodeIgniter\locale_set_default() in /var/www/CodeIgniter4/system/CodeIgniter.php:184[/b]

Code:

[/color]
[color=darkred]public function initialize()
{[/color]
[color=darkred]  // Set default locale on the server
  locale_set_default($this->config->defaultLocale ?? 'en');[/color]
[color=darkred]  [/color]
[color=darkred]

It is late here and I'm off to bed
