For now, I do not see that issue with some products and two products you mentioned in the first comment or variations in the frontend.
If it happens randomly, please let me know when it happens.
Also, you should put the code that excludes groups from caching before the line /* That's all, stop editing! Happy publishing. */ in the file wp-config.php, please check the screenshot attached.
And update WooCommerce Multilingual to the new version 5.3.0 and observe this issue again. Refer documentation https://wpml.org/faq/install-wpml/#checking-for-updates
The issue is not random ! As I explained, if you go to the backend of the website > product list, you will see some tags and categories are in the wrong language (ex : "gold" written in the French product list page, see attached screenshot). And then if you go to plugin > redis and deactivate it, the issue will disappear. I will try what you said and come back to you.
I'm not able to access the staging site again. Can you please help me move your site to a test site that is hosted on the Cloudways server? If it is OK with you, we can migrate your content to further debugging without any risk.
To migrate, please follow steps in the private reply below.
More information: hidden link
You will get an email when the migration starts and one when the migration ends. Let me know when the migration is ready, and I will check the issue on the test site immediately.
The copy of your site will be online, but search engines won't index it (the copy), so you don't have to worry about duplicate content.
The information you share with us will be confidential. Once the problem is resolved, the details you shared with us will be deleted from our records. https://wpml.org/purchase/support-policy/privacy-and-security-when-providing-debug-information-for-support/
Hi there, the migration was done. Please deactivate the plugin called "omnisend" as soon as possible because its creating problem with my remarking emails. Thanks
The lmigratio has failed because of Omnisend actually.. I will recreate a staging site from my end and send you the credential, can you please send me a private info request again ?
I am sorry to insist, but on your screen I can see you didnt really look at all the product list. If you type ctrl+F and search for a French word like "or" or "argent" in the English product list you will find at least 1 or 2 products that have it. And same in the French product list if you look for "silver" or "gold". I swear it happens all the time.
It doesn't work with the word "rainbow" and it doesn't work if you look in the search bar of the website, because it only search the names of the products not the tag or the categories !
I went on the website (didnt change anything) and it took me literally 5s to find it, please look at the screenshot.
