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

If you're experiencing a critical error when switching your WooCommerce product page to a second language, it may be due to a translation issue with placeholders in your theme files.

We found a fatal error related to incorrect placeholder translation in the theme file


on line 1014. The correct format for translating placeholders like "%1$sarticle%2$s" should maintain the 's' after the dollar sign. If the 's' is missing, it will cause an error.

To resolve this, we recommend you:
1. Visit the WPML > String Translation section.
2. Search for the problematic string.
3. Re-translate it using the correct placeholder format.

For more information on translating placeholders, please refer to the WordPress documentation.

We have already fixed the issue for the reported instance, and the translated product should now display correctly on the front end.

If this solution doesn't look relevant to your issue, please open a new support ticket with us.

I am trying to:

Link to a page where the issue can be seen:

I expected to see:
Finnish language

Instead, I got:

Here's what the PHP error says:

Yes, I have tried the following:
- Doing extensive research about this issue before creating a ticket
- Trying to look for the error string, could not find it even with localizing all strings on the site.
- Translating All %s to all languages as it is
- Searcing %s strings and copying them as it is to other languages
- Reinstalling all WPML components
- Deactivating string plugin, this allows the site to works but checkout & cart is then broken
- Installing new language with automatic mode, the new language works, existing languages Finnish and Norwegian are broken

Anything I'm missing from the existing solutions?
