I uninstalled CBSubs, all CBSubs plugins and the CBSubs database tables then completed a fresh install from 1.2.2 files.
Tax is still not showing up when using promotion fixed discount. It is calculating the correct discount, but no tax for the upgrade or the following weeks.
Totalizer Settings: Sales tax is 40, promotions is 20, subtotal is 10 & Grand Total is 100. I tried adding a subtotal 3 at 60 but that made no difference.
Upgrading without promotion does calculate tax.
