Can you check out the other website I have this plugin on. http://www.eastboosterclub.net. The sales tax works with this website. However, the shopping cart widget is to wide on the right side. How do I change the width? Also, the red highlights are hard to read. How do I change color. Thanks for all your help.
I’d suggest checking all of your settings for the tax – if it worked, and now no longer works – then the issue may lie outside of eShop. Also test with no other plugins active and in twenty eleven theme.
