PHP Warning: Invalid argument

This thread is resolved. Here is a description of the problem and solution.

Problem:
After updating the Music Player for WooCommerce and WooCommerce Table Rate Shipping plugins, a PHP warning appeared in the error_log indicating an invalid argument supplied for foreach() in a file related to WooCommerce Multilingual.
Solution:
We have identified that the warning is likely due to a minor incompatibility between WPML and a third-party plugin. However, this does not affect your site's functionality. To remove these warnings, you can modify your wp-config.php file. Locate the line

define('WP_DEBUG', true);

and change it to

define('WP_DEBUG', false);

If this solution does not resolve your issue or seems outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 further assistance is needed, please open a new support ticket at WPML support forum.

Bobby Supporter Languages: English (English ) Timezone: America/Los_Angeles (GMT-08:00)	Hi there, Warnings and Notices in WordPress will not cause your site's function to halt at any time therefore they do not pose a threat to the way your site or plugins are functioning. there is most likely a small incompatibility between WPML and a 3rd party plugin which is not significant enough to cause problems to the way your site is running. you can safely remove these warnings by doing the following Go in your wp-config.php file and look for define(‘WP_DEBUG’, true);. Change it to: define('WP_DEBUG', false);
