Hi Rod

Just wondering if you can help me. I have ozpost installed and i have set the error amount up but when a customer orders alot and it goes back to my error amount the customer can't use it. It wont let them past step 2 in the check out and when it does it brings up a error screen saying the webpage format is not supported do you know what this could be.

Thanks

Here it is again just incase you missed it
