Hi Frank @frankbiganski,
Thank you for sharing a detailed description on the issue you’re facing.
Looking at the error log you’ve shared, it indicates that the function is deprecated since version 6.3. This means that this function is no longer recommended for use in the newer versions of WooCommerce.
However, as you’ve mentioned that you can process test payments and customers are placing orders without any issue, it seems that this deprecated function is not causing any operational problems at the moment.
That being said, it would be a good practice to update your WooCommerce plugins and themes to the latest versions, as they will have the updated functions that replace the deprecated ones. This will ensure that your site continues to function smoothly with future updates.
I hope this helps.
