Attempted to load class "IntlTimeZone" from the global namespace. Did you forget a "use" statement?

I just upgrade from Joomla 3.10 to 4 / php 8.0 thinking I will lose this extension and was amazed to find that you "reload" it, thanks.

The install was fine and the admin works (all my polls stay there), but as soon I try to load a module Joomla crash with the above message:

Attempted to load class "IntlTimeZone" from the global namespace.
Did you forget a "use" statement?

Exceptions 2 / Stack Traces 2
Symfony\Component\ErrorHandler\Error

in D:\Shorted\ServerJ4\www\components\com_sexypolling\helpers\helper.php (line 171)
//load language and timezone
$lang = JFactory::getLanguage();
$lang->load('com_sexypolling');
$lang_tag = $lang->getTag();
$iterator = new ArrayIterator(iterator_to_array(IntlTimeZone::createEnumeration(substr($lang_tag, -2))));
$iterator->rewind();
$time_zone = $iterator->current();
setcookie("sexy_poll_lang_tag", $lang_tag, time()+36060, '/');
setcookie("sexy_poll_time_zone", $time_zone, time()+36060, '/');

Any idea to solve that?

Thank you for testing the reloaded plugin!

The IntlTimeZone class should be included in your PHP installation. IntlTimeZone is part of the PHP "intl" extension. If I deactivate the "intl" extension in my installation, I get the same error message.

Can you check your php.ini file, if the "intl" extension is activated. Your php.ini file must contain the following line:
extension=intl

That is. Now it is working as in 3.10. Thank you very much.
