Problem:
If you're experiencing a critical error on your website after installing WPML for WooCommerce, it might be due to using an outdated version of the WooCommerce plugin.
Solution:
We recommend updating your WooCommerce plugin to the latest version (Version: 9.4.2) to ensure full compatibility. After updating, try reinstalling and activating the WooCommerce Multilingual plugin. This should resolve the issue.

If this solution does not apply because it might be outdated or not relevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If you still need help, please open a new support ticket at WPML support forum.
