    Hello,

    We’re encountering a fatal error when accessing the WooCommerce product admin page. The issue appears to be caused by an undefined constant WPML\WPML_PLUGIN_FOLDER in the WooCommerce Multilingual plugin (UIPage.php:45). It looks like the plugin is attempting to use a constant from WPML that may not be defined or properly loaded. WPML core may be missing, inactive, or there’s a version mismatch between WPML and WCML.

    Steps to reproduce:

    1. Go to WooCommerce > Products in the WordPress admin
    2. Fatal error is thrown, preventing access to the product list

    Error Level: E_ERROR
    Message: Uncaught Error: Undefined constant “WPML\WPML_PLUGIN_FOLDER” in /home/WEBSITEPATH/wp-content/plugins/woocommerce-multilingual/addons/wpml-dependencies/vendor/wpml/core-api/core/UIPage.php:45

    We’d appreciate guidance on resolving this compatibility issue.

    Rolling back to 5.3.9 fixes the issue. It also fixes the product quick edit which was broken. Seems the latest version is causing a few issues.

    Hi @devksec,

    Thanks for your report!

    Indeed, it seems like a bug in our latest version (5.4).

    It throws a fatal error in the admin footer of the product list screen on servers with PHP8+. And the symptom is that some features are broken, like “quick edit” of products.

    As a quick workaround, I would suggest to add the following line in your wp-config.php file:

    define( 'WPML_PLUGIN_FOLDER', 'sitepress-multilingual-cms' );

    We’ll try to fix it as soon as possible.

    Note: Once it will be fixed in next WCML patch version, you should remove the workaround.

    Thanks,

    Pierre

    Hi @devksec,

    With released WCML 5.4.4 which should fix the problem.

    Let us know otherwise or close the ticket.

    Thanks,

    Pierre
