Hi,

Thanks for your support. If I try to add this code, I have this error:

Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function "yith_wcan_change_terms_limit" not found or invalid function name in wp-includes/class-wp-hook.php:308
Stack trace:...

How can I fix?

Thanks
