2. Filter labels not translated initially
- Labels (e.g. “Преди раждане”) show in Bulgarian on first load
- Only after applying a filter (AJAX), they switch to German
3. Inconsistent AJAX behavior
- Initial state ≠ post-filter/reload state
4. What we checked:
- Categories fully translated (names + slugs) via WPML Taxonomy translations
- Taxonomy set to “Translatable – only show translated items”
- AJAX language cookie enabled
- Caches cleared, permalinks resaved
- WooCommerce lookup tables regenerated
5. Questions:
5.1. Is the WooCommerce Product Filters block fully WPML-compatible?
5.2. Does ?categories= play a role in the filtration in the different languages and if so, how can we translate it?
5.3. Why does multi-select produce mixed-language slugs while single-select works?
6. Expected:
- Consistent translated slugs: /de/shop/?categories=german-slug-1,german-slug-2
- Filter labels translated on initial load and after AJAX
You can reproduce the issue here: hidden link, these are the fields in question: hidden link. They should be in German, not Bulgarian. They are added from: WP admin -> Appearance -> Widgets -> WooCommerce sidebar.
You can access the website administration from: hidden link
I'd like to request temporary access (wp-admin and FTP) to the website to investigate the issue further.
You'll find the necessary fields below the comment section if you log in to leave the next reply. The information you provide will be private, meaning only you and I will be able to see and access it.
IMPORTANT
Please be sure to create a backup of the website and database before granting us access.
If you don't see the "wp-admin / FTP" fields, your login credentials for the post and website will be set to "PUBLIC." Do NOT publish the information unless you see the required wp-admin / FTP fields.

Hi Andreas, I'm not seeing the private field, only this: hidden link. I can't edit my previous message either to potentially include this information in a manner you need. What to do?
Hi, for some reason a lot of our Shop page settings were changed - including that the pages is created and edited via Elementor, which it was not originally. Is this something you were testing maybe?
Apart from that, we reverted the changes we noticed but still the filters weren't showing at all, even on our primary language. They are only showing if the WP_Debug is enabled. I'm assuming you're testing something? We haven't made any changes from our live website since we sent to you to debug.
EDIT after additional debugging on our end:
WooCommerce Product Filters category filter disappears when WP_DEBUG is false. It appears and works correctly, including translated labels and slugs, when WP_DEBUG is true with WP_DEBUG_DISPLAY false. SCRIPT_DEBUG true alone does not help. WooCommerce lookup tables/transients/recount terms did not help. Reinstalling/updating WPML + ACFML fixed previous fatal errors, and no new debug log errors appear.
Adding this in after further digging:

I had to go to Appearance > Widgets and save the block again to make it visible.
I do currently see translated filters, which seem to work. Only the title "Филтри" was not translated, but I adjusted this on WPML > String Translation.
Please verify and let me know if further assistance is needed.
Hi, yes, right now they are working, but for some reason, when define('WP_DEBUG', false); the filters disappear from both pages: hidden link. Could you please explain why that is and if possible to change it? We don't necessarily want the debug enabled at all times.
No, when I disable the WPML plugins and set define('WP_DEBUG', false);, the filters are still correct in our now only language version: hidden link. You can check for yourself now, I've left them inactive.
Please also list all the changes you did on your end so far, so we can transfer them to live?
