[Resolved] WPML integration goes wrong with custom vamos funnel plugin

Problem:
The client is experiencing issues integrating WPML with a custom funnel plugin (Vamos Funnel) for a multilingual WooCommerce site. The main problems include incorrect loading of translated product data, increased loading times, and mismatched translation strings across different languages.

Solution:
1. Ensure the custom plugin follows WordPress coding standards and uses WPML-compatible hooks and APIs. Review the guide on Achieving WPML Compatibility for Your Themes and Plugins for detailed instructions.
2. Increase the WordPress memory limit to at least 256MB by adding the following code to wp-config.php:

/* Memory Limit */<br />define('WP_MEMORY_LIMIT', '256M');

3. Consider re-architecting the funnel or using a different plugin that has built-in WPML support if integration issues persist.
4. Test the integration on a staging site with minimal setup to isolate issues.
5. If necessary, pivot to a simpler multilingual strategy or a different funnel plugin that is known to work well with WPML.

If these steps do not resolve the issues or if the solution seems outdated or irrelevant to your specific case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the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.
