Hello,

Which Arastta version are you using there?
Which mode are you using? The Basic or Advanced mode?
Did you install any other extension? If yes, please disable them and try again.

Best Regards.

Hello, i am using the latest version. i have close a extension and it is working now. Thanks for your help.
The extension i tried is to put prices incl. VPA at a product. Now i only can put a price excl. VPA to a product.
Best regards.

Hello,

So ask developer about this issue because his/her extension is causing it.

Best Regards.

Oke, let you Know..
