WooCommerce Multilingual & Multicurrency causes 504 Gateway Time-out error

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

Problem:
If you're experiencing a 504 Gateway Time-out error when trying to update a variable product with WPML and WooCommerce activated, the issue might be related to the server not receiving a timely response from an upstream server it needed to access.
Solution:
First, ensure you have the latest version of the WPML plugin and its add-ons. You can find the latest versions in the 'My Account -> Downloads' section of the WPML website. For instructions on how to update, please visit http://wpml.org/faq/install-wpml/. Remember to back up your database before updating, using a plugin like Duplicator (http://wordpress.org/plugins/duplicator/).

Additionally, try increasing the PHP Max Input Vars on your server to 10000.

We've made some improvements in the latest release of WooCommerce Multilingual plugin.

If the solution provided here is irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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 assistance, please open a new support ticket in the WPML support forum.
