Variable product attributes not matching images and prices on English version

This thread is resolved. Here is a description of the problem and solution.

Problem:
You have created a variable product in French on your WooCommerce site, and while it works perfectly in French, the English version has issues with mismatched variation images and incorrect pricing. This problem occurs when switching to the English version of the product.
Solution:
After extensive testing, we discovered that the issue is related to the PHP version used on your server. Specifically, the problem replicates with PHP 7.4.33 but not with newer versions. We recommend updating your server's PHP version to at least PHP 8.1 or PHP 8.2. After updating, please test the English version of your product again to see if the issue persists.

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If problems continue, please do not hesitate to open a new support ticket with us for further assistance at WPML support forum.

Lauren WPML Supporter since 10/2015 Languages: English (English ) Timezone: America/New_York (GMT-04:00)	After further testing, neither myself nor our second tier are able to recreate the issue when creating a new product, or translating from scratch. I realize you are still able to reproduce the issue, but we can't figure out what we are doing differently. I translated the attributes, set backorder, etc. The previous screencast has since expired. I hate to ask you this but could you please record the full process of you creating a brand new product in the staging site and record all the steps through tranlsation? I think this is the only way we will be able to reproduce the issue. I appreciate your continued assistance and patience.

kisa	Hello Lauren, No worries. I recorded the process again while creating and translating a product, and unfortunately, you'll see that the issue still persists... hidden link

Lauren WPML Supporter since 10/2015 Languages: English (English ) Timezone: America/New_York (GMT-04:00)	Okay after much testing, I think we have isolated the issue. On a local test site, we were not able to reproduce the isuse. Also on a local copy of of your site, we were not able to reproduce. Our 2nd tier support was finally able to reproduce it on the staging site on your server. Having established that it appears to be server related and eliminated differences such as MU and drop-in plugins on the client server, they noticed that you are using PHP 7.4.33. He updated his local environment to use the same (well, 7.4.30) on an Apache server, and then he could replicate the problem locally, too. So, it only happens with many variations, when using and older version of PHP. Would it be possible to update to PHP 8 (Actually, 8.0 has already officially reached end-of-life, so maybe 8.1 or 8.2.)? Let me know if you can do that and test and then if the issue is still happening.

kisa	Hi, I’ve just updated the PHP version to 8.2 — could you please confirm if this also applies to the staging site? I’ve also run another test on our live site, which should now be running on PHP 8.2 as well, but the issue still seems to persist. At the moment, we’re even sometimes getting the message: "Sorry, no products matched your selection. Please choose a different combination." on a variation, even though the base language shows the products as being in stock. Thanks in advance for your help!

Lauren WPML Supporter since 10/2015 Languages: English (English ) Timezone: America/New_York (GMT-04:00)	yes, please update on the staging server as well. Can you please share a screencast of you testing this onthe staging site with the updated PHP and if you can, include that message, so I can send it back to our 2nd tier support. Thanks, I was certain we had narrowed it down this time!

kisa	I just recorded a new video on the staging site using the updated PHP version: hidden link And it seems to be working! I'm not sure why it's still not working on the live site though—maybe it only applies to newly added products? Tomorrow, I'll try creating a new product and translating it on the live site to see if it works, and I’ll let you know. THank you again for your patience and your help!

Lauren WPML Supporter since 10/2015 Languages: English (English ) Timezone: America/New_York (GMT-04:00)	Okay that's kind of good news I guess? Let me know what you find tomorrow and I can go back to our 2nd tier support as needed. Thanks again for your help with the troubleshooting.

kisa	Hi Lauren, Thank you so much! I really feel like the issue was related to the PHP version, as everything seems to be working fine now. I can hardly believe it! T_T I just hope it continues to work smoothly. Thanks again for all your assistance, I really appreciate it! Best regards
