    Can someone please help stop these errors so they do not clog up our log files? It is being thrown multiple times per second, as seen below.

    Hi @loafintree ,

    Thanks for reaching out!

    It looks like WooCommerce is throwing PHP warnings due to undefined array keys in the MetaToMetaTableMigrator.php file. This can sometimes happen after updates or certain changes in your environment.

    To get this sorted, I’d recommend the following:

    Ensure WooCommerce is up-to-date: Double-check that you’re running the latest version of WooCommerce. Sometimes these kinds of warnings are addressed in updates.

    Suppress warnings temporarily: If you’d like to hide the warnings for now while you’re troubleshooting, you can add this line to your wp-config.php file: 

    error_reporting(E_ALL & ~E_WARNING);

    This will prevent the warnings from being logged. Keep in mind, though, this is just a temporary fix to keep things running smoothly.

    Test with a different PHP version: If you’re still having trouble, it might help to try downgrading to an earlier version of PHP temporarily. Sometimes newer PHP versions can cause compatibility issues with older plugin code, and reverting to a more stable version might clear things up.

    I hope this helps!

    Hi there,

    As we haven’t had any updates, I’ll assume this is resolved and close the thread. Feel free to reconnect anytime.

    Apart from this, if you’re happy with our plugin and the support you’ve received, we’d really appreciate a review: https://ww.wp.xz.cn/support/plugin/woocommerce/reviews/#new-post
