I did an update of the woocommerce plugin. Because I have custom changes I uploaded the files with the custom changes. It is about a new tab with an additional image: http://www.kriesi.at/support/topic/woocommerce-additional-image-tab
But after I did that it works as before only there is some error showing up:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'woocommerce_google_tracking' not found or invalid function name in /public/sites/dev.vonorangesup.com/wp-includes/plugin.php on line 4051
Why is that and how to fix this.
Thanks a lot,
