Site Crashed U_ILLEGAL_ARGUMENT_ERROR in IntlDateFormatter

[pilou2]

Noting that the zcDate.php class is PHP version-specific, using strftime for PHP versions < 8.1 and using the IntlDateFormatter class (if that PHP extension is installed) otherwise.

I did not do detailed explanation as it was already explained few month ago but I made it backward compatible. It uses IntlDateFormatter (PHP >=5.3.0 with PECL >=1.0.0) if avialable as it is possible (although very rare) to remove this extension in PHP settings, then date_format (PHP >= 5.2.0) if not. Strftime % parameters are accepted as input parameters.
Compatibility should go back to ZenCart 1.3.9 although I did not test it and won't... This was made for Zencart 1.5.8 (PHP >= 7.3) and above anyway.

post 7 by dr byte fixed this issue for me.

for those reading/searching on solution why php 8.1 and 8.2 white screens the site and php 8.0 works fine.
fresh install tested. 1.5.8a

My bad. Turns out 'en' alone isn't "valid" either. And that's what I had in my clipboard when I pasted. Doh!

EDITED: now recommending:

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

Add this to the end of includes/configure.php and YOUR_ADMIN/includes/configure.php

That fix for a blank store with the log "Uncaught Error: Found unconstructed IntlDateFormatter" worked for me! I changed the two cofigure.php files and now both the customer-facing page and the admin page load on my test install.

That fixed worked for me when the customer-facing page and the admin page were both blank and the log listed an "Uncaught Error: Found unconstructed IntlDateFormatter". Thanks.

Hi Guys,
I tested 1.5.8a fresh install with PHP 8.11 and tested all patches without sucess. When using PHP 7.4 all it works without problem. I assume if PHP 8.0 is used it will also work, as per other forum posts(also tested php 8.010 and it works). 2.0 is supposed to solve this issue. The important question for us is the compatibility of the plug ins in version 1.5.8a and 2.0. If the plugins are compatible with both these versions then we go straight to version 2.0. If not we have to sort out the issues with 1.5.8 till the 2.0 with our pluggins are compatible. Any hints of what we maybe doing wrong with the PHP 8.1+ patch is welcome.

I'm not clear on what the issue you're facing is; see post #24 in this thread ... has that change provided by DrByte been applied?

Hi Cindy,
The patch @setlocale(LC_TIME, ['en_US', 'en_US.UTF-8', 'en-US']); has been applied to both configure files without success. I initially use GB instead of US but at the end I used the exact statement above. I tried also to changed the Time Zone to Europe/Athens but without success.

When going back to PHP 7.4 or 8.0 the blank pages go away and the the store works as expected.

The logs are the shown below

Still trying to figure out what's going on. This link: https://github.com/zencart/zencart/b...te.php#L87-L91

... identifies lines 87 through 91 of the zcDate.php class for zc158a. The fact that your logs show an issue being thrown on line 90 is what's (er) throwing me off.

Setting on line 90 'none' means it uses PHP's or system's default. There might be some bad setting in php.ini or somewhere on the server, just an idea.

The error getting thrown could be the result of date.timezone not being set correctly in php.ini.
