IntlDateFormatter php issue

ZC 1.5.8 (probably others too)
Due to changes of IntlDateFormatter in PHP 8.1.25 8.2.12
any store updating to those new releases of PHP will get a server 500 error, and logs like below.
Here it the github info on the change : https://github.com/php/php-src/issues/12561
What I don't know is what we have to change to fix it.

Sort term answer is drop down to PHP 8.0

Code:

Since I can't delete, see this thread for better info https://www.zen-cart.com/showthread....ARGUMENT_ERROR

The fix for this issue from Dr. Byte is as follows:

Zen Cart 1.5.8/1.5.8a users: Add this to the end of includes/configure.php and YOUR_ADMIN/includes/configure.php:

Code:

---

@setlocale(LC_TIME, ['en_US', 'en_US.UTF-8', 'en-US']);

This issue is handled in 2.0.0 without the requirement for these changes.
