Problem: The client is encountering a PHP warning on every product page related to the WPML plugin, specifically a preg_match() error in the absolute-links.class.php file. Solution: 1. We recommend re-saving the permalinks on your site to see if this resolves the issue. 2. If the problem continues, please disable all plugins except for WPML, WooCommerce Multilingual & Multicurrency, and WooCommerce to check for a possible plugin conflict. 3. Before making any changes, ensure you have a complete backup of your database. 4. We also asked the client to provide debug information by following the instructions at http://wpml.org/faq/provide-debug-information-faster-support/.
Please note that the solution provided might be outdated or not applicable to your case. If the issue persists, we highly recommend checking the related 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 do not hesitate to open a new support ticket. For further assistance, you can reach out to us on the WPML support forum.
