Hello I bought the Order Editor Extension
http://www.opencart.com/index.php?route ... on_id=3448
I use Opencart 18.104.22.168
If i change a product or add 1, the tax rate is changed to 63%
The Tax rate should be 21%
I tried it with the Vqmod version and also the manual install both the same problems.
Vqmod version installed at this moment.
I don't know how to solve this, the developper does not react of any kind of communication.
Hope someone can help me to solve this.
