Background of the issue:
I am trying to translate product options using the YITH WooCommerce Product Add-ons & Extra Options Premium plugin. The options are translated, but the selected number is not working in languages other than the default. You can see the issue on this page: hidden link.
Symptoms:
The number of added stickers is only visible in the cart, checkout, and WooCommerce order details in the default language (co.uk), but not in other languages.
Questions:
Why are the translated product options not working in languages other than the default?
How can I make the number of added stickers visible in all languages?
I am truly sorry for the mistake. I didn't realize that your site was using domains per language and thought that NL was the default. Please apologize.
I would like to request temporary access (wp-admin and FTP) to your site to take a better look at the issue.
It would be better to a testing site where the issue is replicated.
The information you will enter is private which means only you and I can see and have access to it.
Maybe I'll need to replicate your site locally. For this, I'll need to temporarily install a plugin called “Duplicator” or "All in One WP Migration" on your site.
This will allow me to create a copy of your site and your content.
Once the problem is resolved I will delete the local site.
**IMPORTANT**
- Please make a backup of site files and database before providing us access.
- If you do not see the wp-admin/FTP fields this means your post & website login details will be made PUBLIC. DO NOT post your website details unless you see the required wp-admin/FTP fields.
I took a new copy of your site (I finally used Updraft Plus, the other plugins failed). And deployed it locally. And it just worked. Take a look at the screenshot attached.
So, I suspect a caching issue, some server optimizations that may be manipulating JS code, or, as I needed to disable domains per language, the URL format.
Can you please check that? Switch for a moment to languages in directories in WPML > Languages > Language URL format and check if the fields appear in the checkout.
If not, can you please confirm if there is any server caching or optimization in place?
Its not an option to not use language per domain as we have like 6 domains that just need a different language, all works fine to only that little stupid attribute of the product add-on does not work besides the main site eancodeshop.co.uk.
We have a litespeed server but don't use any caching so caching is ruled out.
It does have many JS code located at the snippets but it does not seem to handle the attributes/product add-on texts. Its most likely a WPML issue.
Also for eancode on stickers it does work.
Only on buy eancodes products its doing something why it dont work in cart and checkout.
I just debugged something and it might be the reason.
For stickers the variation class in the cart (which works) is the same:
It does not look related to the class either. Locally, I have the same, and it's working 🤔. Check the screenshot attached.
I also tried locally setting a domain per language, and it still works. Check the other screenshot.
The local clone works flawlessly, so the problem seems linked to something that exists only on the live LiteSpeed server (caching/optimisation, object-cache, HTTP headers, or domain rules) rather than to WPML + YITH themselves.
In the production site, I don't see any errors on the console. Can you please check if there is any PHP error:
Please follow the instructions mentioned on this page: https://wpml.org/documentation/support/debugging-wpml/
Then, go to the checkout and check your installation's **wp-content** folder to see if a file named **"debug.log"** was created (it will only be generated if a server error occurs).
If the file was created, please upload it to a platform like **Google Drive** or **Dropbox** (whichever you usually use) and share the link with me (make sure it is publicly accessible) so I can analyze it.
It's hard for me to test and debug things as the problem is not happening in my local environment. Is it possible for you to provide us with a staging site where the issue is reproduced?
