I have been using this extension since I launched the website at the end of April without any problems. A few days ago a number of customers advised us through facebook that they could not complete their purchases.
I am using the latest Woocommerce and extensions on another website and there's no issue. It seems to be a conflict with this theme. So far I have no real solution from Woo. They said they would look into it but I haven't received any update.
I'm not having any luck myself trying to figure out what the conflict is with the theme. Anyone have any suggestions?
The following is the error message I get when going to the cart or checkout.
Error Message: Fatal error: Call to a member function children() on a non-object in /public_html/wp-content/plugins/woocommerce-austpost/hypnoticzoo_utilities.php on line 84
Line 84 is

Thanks in advance.
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
