[En attente du retour de l'utilisateur] 503 error on WPML woocommerce multilingual

Hello there!

I have asked a french speaker supporter to take your case but while he starts I'd like to tell you that I saw the debug log lines you sent us:

[17-Jul-2025 07:02:58 UTC] wc_get_product was called incorrectly. N'appelez pas wc_get_product avant l'exécution des actions woocommerce_init, woocommerce_after_register_taxonomy et woocommerce_after_register_post_type.

Now, these aren't errors, they are notifications meaning that they are not the ones that create the 503 error, but may be related to the main problem.

I'd like you to follow a few steps and let me know the outcome since they will probably help us understand where the problem lies:

1) Can you temporarily disable the WP Forms plugin? it's creating a notification because of a missing language (spanish) that it tries to read, probably because you've enabled Spanish on your site. this way we remove one error from the debug.log

2) One of the notifications reads " wc_get_product was called incorrectly. N’appelez pas wc_get_product avant l’exécution des actions woocommerce_init"

This means that you either have a WooCommerce Extension doing something at a wrong time OR that you have custom code for WooCommerce that might be ok but it's hooked incorrectly.

2.1) Can you tell me if you have custom code on your theme about WooCommerce?
2.2) Can you try to disable the WC Related plugins and leave only WooCommerce Multilingual and Woocommerce Enabled. Preferably on a theme like Storefront or a default WordPress Theme like TwentyTwenty Five, just to see if that 503 error still appears.

PLEASE NOTE

- We never suggest you run these tests on a LIVE site. You can use a plugin like lien caché">WP Staging to create a quick staging site and test there

- If you do decide to do this on a live site, please create a site backup. these tests should not break anything but it's better to always have a secure "checkpoint" to return to.

- Make sure the debug.log is enabled and check it after each test or send us the file after you run your tests (you can upload them to a place like wetransfer, dropbox or any other similar service and share the links with us, they will be private by default!).
