Hi to all, in the InOnda Store subsite error_log, from InOnda.tv WordPress multisite installation, I have a periodic warning message about "woocommerce_attribute"... The message is:
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'woocommerce_attribute' not found or invalid function name in /xxxxxx/public_html/wp-includes/class-wp-hook.php on line 298
I want to solve the issue but I don't know its nature and what I should do.
Can you help me?
