    Hi after the recent update to Version 1.0.7 I got the following Warning which appears on the product side:

    “Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘WPM_Product_GTIN_WC’ does not have a method ‘wpm_structured_data_product’ in /srv/www/…/wp-includes/class-wp-hook.php on line 290

    Do you have any Idea why?

    Before update everything worked fine witout warning message and all plugins and woocommerce are updated to the most recent update.

  • Have something similar here:

    call_user_func_array() expects parameter 1 to be a valid callback, class ‘WPM_Product_GTIN_WC’ does not have a method ‘wpm_structured_data_product’

    Same here. I’m getting a critical error. I have had to disable this plugin. ??

    Hello there,
    I’m sorry for this. I released a new version with the fix.

    Many thanks for the fast fix.

    Since yesterday I am not receiving the GTIN in the emails for new orders. It appears that it is also missing from the order itself so not being added as an order item meta.
    I have checked the box is ticked to save the meta and it is indeed still on the product page. Is there a setting that has been added or deleted that I am missing?
