Problem: If you're experiencing a conflict between the WPML plugin and the WooPayments payment system, which prevents customers from making payments, follow these steps to diagnose and potentially resolve the issue. Solution: 1. Create a staging site with a copy of your production site. 2. Deactivate all plugins, including WPML ones. 3. Activate a default WordPress theme, such as Twenty Twenty. 4. Enable WordPress debug mode as described in this guide: https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/ 5. Reactivate the WPML plugins, WooCommerce, WooCommerce Multilingual, and WooPayments. 6. If the issue disappears, reactivate your theme and then other plugins one by one to identify the culprit. 7. Monitor and share any fatal errors from the debug.log file in the wp-content folder.
Please note that this solution might be outdated or not applicable to your specific case.
