 * One of the sites that I assist with just recently started getting “There has 
   been a critical error on your website”.
 * This seemed to be related to WF as when disbaled it did not occur. I did find
   some posts also identifiying WF and suggesting to uninstall, clean and reinstall.
   I have done that and I do not seem to be getting the above error.
 * However on the checkout page we are using the WooCommerce Australia Post Shipping
   extension which looks up the postage cost. When WF is active the cart cannot 
   ontain a postage quote and is just stuck spinning. When WF is disabled a delivery
   cost is returned.
 * Can anyone suggest how we can stop this function from being blocked?

 * Have you tried putting the firewall into learning mode and then obtaining a postage
   quote? Make sure and try from a browser that isn’t logged in since this is something
   I think the customer/visitor will do, right? If it works, then do it a few more
   times. Then set the firewall back to enabled and protecting and try to obtain
   a postage quote from a browser that isn’t logged in again. This should have whitelisted
   the action. Either way, let me know.
