Problem: The client is experiencing an issue where adding a variable product to the cart results in infinite loading. This problem only occurs when the WPML Multilingual CMS plugin is enabled. Solution: We recommend isolating the issue by simplifying the site environment. Here are the steps we suggest: 1. Switch to a default WordPress theme, such as TwentyTwenty-Four, to check if the issue persists. 2. If the problem still occurs, deactivate all plugins except for WPML and its add-ons, and WooCommerce, without any extensions. Test again. 3. If the issue resolves, reactivate the other plugins one by one to identify which one causes the conflict. *** Important! Please make a full site backup (files and DB) before you proceed with these steps*** *** If your site is live, you might want to try these procedures in a staging environment or a snapshot of your site on your local server or another server. *** The client reported deactivating the Query Monitor plugin solved the problem.
If this solution does not apply because it might be outdated or not relevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 the issue persists, please open a new support ticket at WPML support forum.
