Good morning
A customer just informed me about a problem of taxes calculation yesterday, the VAT was displayed even when a product has to go abroad (thus normally no VAT displayed of calculated).
Since we have several warehouse, tax rules and shipping methods it could have been a parameters issue, despite we never noticed an issue before.
The strange point is that after changing the shipping method or even refreshing (the checkout) page without doing anything else, the VAT disappeared, which is correct.
I downloaded and installed the last release ok Hikashop and it fixed immediately the problem. Maybe because of Joomla 3.7 or other reason, but it may be worth trying to do this in case of taxe issues before reviewing all the parameters
Sorry in advance if I am wrong but it worked for me!
