Support » Plugin: WooCommerce Zettle Integration » Continuous errors logged / images

  • Resolved Jaakko Pöntinen


    Heya 🙂

    Upon importing (manually) all my products from Zettle – some 180 of them. I keep getting the two errors below logged by the hundreds. This is not a problem per se, as the import is working fine, or so it at least seems.

    PHP Notice:  Array to string conversion in /data/wordpress/wp-content/plugins/woo-izettle-integration/includes/izettle-integration-iz-products.php on line 1355
    PHP Warning:  sprintf(): Too few arguments in /data/wordpress/wp-content/plugins/woo-izettle-integration/includes/izettle-integration-iz-products.php on line 1355

    Another thing is that the process of getting images is s – l – o – w 😀 Maybe 2 images get imported per minute! Refreshing WP media library every now and then reveals that the import is bringing the images in, but the rate is, uh, sub-par 😀

    Sorry to hear that you do experience problems.

    The issue that you are referring to is a known bug and will be corrected in the next version (later this week). Send an email to if you do want a pre-version.

    The very low import rate of images is linked to the first issue, when the import crashes the action scheduler will wait some time before starting -> giving a slow behaviour.

    Thanks for the lightspeed reply 😀

    No worries, I’ll wait – my import is almost done and the plugin works beautifully otherwise.

    This is one of the best POS/PIM-integrations I’ve ever configured. And I know lots of professionals here in Finland think so, too. Another plugin of your making is also gaining momentum, “WooCommerce Accounting Report”. It’s just beautiful. Woo is made for North America and it shows in the way things are organized and presented. We need EU approach and of course even closer to home, Nordic approach.

    Keep it up and thanks again!
