I am trying to:
Switch from PHP 7.4 to PHP 8.1 on our WordPress site with WooCommerce & WPML.
Link to a page where the issue can be seen:
On our site, also discussed here: https://wordpress.org/support/topic/critical-error-with-php-8/
Until I found out that the site it functioning with PHP 8 and "WPML String Translation" deactivated. There are some technical comments from the WooCommerce team.
I expected to see:
No problems with PHP 8. 🙂
Instead, I got:
A critical error from WordPress and the following error report mail:

Hello, the thread you mentioned is the same thread I mentioned above and it was started by me before I came here because it turned out that the error is somehow in translations and not in WooCommerce.
Also I just tried using PHP 8.0 and it is the same as with 8.1, WordPress will work as long as "WPML String Translation" is inactive. Once I activate it, critical error.
WordPress-Version 6.0.1
Aktives Theme: Deli (Version 2.0.15)
Aktuelles Plugin: WooCommerce (Version 6.8.2)
PHP-Version 8.0.22

One addition: Because "WooCommerce Multilingual & Multicurrency" is inactive when "WPML String Translation" is deactivated, I guess the bug could very well be in there. But it is also a OnTheGo/WPML plugin.
However when I deactivate only "WooCommerce Multilingual & Multicurrency" and leave "WPML String Translation" active before switching to PHP 8, the critical error will still occur.
I can confirm that WPML itself is also not compatible with 8.0.1 yet, however, we should be compatible with PHP 8
I would like to request temporary access (wp-admin and FTP) to your site to test the issue.
(preferably to a test site where the problem has been replicated if possible)
**Before we proceed It is necessary to take FULL BACKUP of your database and your website. Providing us with access, you agree that a backup has been taken **
I often use the Duplicator plugin for this purpose: http://wordpress.org/plugins/duplicator/

1. I have not been able to reproduce this issue with a new install of WCML + WPML + WooCommerce + PHP 8
NOTE: Yes I am only reffering to any PHP 8.1.x version PHP 8.0.x should be fine with WPML and WordPress
2. In my local environment with a copy of your environment I can confirm the issue exists from 7.4 to 8.0.x
It is resolved when changing your theme from Deli to a standard WP theme.
I'd recommend reviewing the code you receive as it points to a specific string, also it is a WooCommerce theme, I believe their team should have been able to point out more information.
Let me know your results with this new information
At the moment I am not able to reproduce with a clean environment and cannot reproduce when the theme is switched from Deli.
I tried to switch to PHP 8 with another active theme than Deli; Storefront, Twenty Twenty and Twenty Twenty-Two. It does always result in a Critical error and I have to switch back to 7.4, so for my site it does not seem to be related to the Deli theme.
When I get a mail from WordPress about the critical error, it always occurs in wp-content/plugins/woocommerce/includes/class-wc-post-types.php:234 (same error message as in previous post).
And, the site does work well with PHP 8 when "WPML String Translation" is deactivated.
I also tried once again with WP Debug Mode enabled. Following to a lot of "warning" and "deprecated" notices, exactly the same fatal error with identical stack trace occurs.
So for me it seems, the only option for now is to stick with PHP 7.4?
I have been testing with Duplicator PRO on the local environment and cannot reproduce it only when using the theme Deli which uses a copy of your site.
Being that I cannot reproduce and we don't have any other similar known issues it would be tough for our team to debug
Have you been able to test locally? Possibly in a different environment from your current hosting env ?
