Background of the issue:
I am trying to make my WooCommerce website multilingual using WPML. The base language is Turkish, and I am adding English and Dutch as secondary languages. My setup includes WooCommerce, WooCommerce Subscriptions, a 'Product Fields' plugin to add custom options to products, and a 'Side Cart' plugin. The main Turkish version of the site works perfectly, and the translated homepage, menus, and main shop archive page display correctly.
Symptoms:
When I try to access a single product's translated page in English, it results in a 'There has been a critical error on this website' screen.
Questions:
Could you please analyze this situation?
Does this pattern point to any known issues or conflicts?
Is there any other way you can recommend to diagnose a fatal error that is being suppressed by the server?
