i used this plugin for my old project. It was very useful. But im not sure still active or continue developer support.
I have same problem on 1.6.1.6.
But is very strange, I can put 123,98 € (incl. 12% tax) price but when i try 123,99 system change to 124€ ??
Have any solution for this?
I've the same problem!
Im use different countries with different tax. Sweden tax 25%, Norway tax 0% so when customer change to countries prices don't change. Needed refresh several times.
But when you add product cart show correct prices.
Prestashop ver. 1.6.1.4
Smarty (Force compilation) and cache turn off.
Somehow i have to forced clean browser cache when customer change to countries (language).
Any idea?
Thanks
