PHP Error/Warning

Hi @nick7766,

Thanks for sharing this PHP warning.

Do you still get this warning when you disable all plugins except WooCommerce and switch to the default Storefront theme? Can you confirm all your plugins/extensions are up to date?

Could you please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”. Once you’ve done that, paste it here in your response.

Thanks.

I am receiving the same error in my log file.

[16-Oct-2021 03:43:05 UTC] PHP Warning: array_column() expects parameter 1 to be array, string given in /home/xxxxx/public_html/wp-content/plugins/woocommerce/packages/woocommerce-admin/src/RemoteInboxNotifications/Transformers/ArrayColumn.php on line 27

WooCommerce has yet to be updated to 5.8, but everything else looks up to date. Here is my system status report…

Hi @pls77,

Do you receive this same error message if only WooCommerce and the Twenty Twenty theme are active?

Thanks!
