Problem: The client reported an issue with an infinite loop caused by an unused filter in the Ultimate Gift Cards for WooCommerce plugin. Solution: We asked the client to isolate the issue to determine if it was specific to their site configuration or a general issue with the combination of Duracelltomi Google Tag Manager & WPML. We provided a sandbox environment and instructed the client to: 1. Access the provided sandbox link. 2. Download and activate the Duracelltomi Google Tag Manager and the plugin in question. 3. Create a simple product and attempt to replicate the issue in the cart. We also advised the client to focus only on the theme/plugin and the related functionality without setting up a full website or cloning their existing site. For further guidance on how to reproduce issues, we provided a documentation link: https://wpml.org/faq/how-to-reproduce-issues-and-share-them-with-wpml-support/.
