Hello,
I have changed nothing in articles on my test webshop. But for every of my article ( I have about 50 + charachteristics) I get a limit message when I order more than 12 pieces of an article. Less than 12 is no problem.
It happens with all of my articles???

I can't see what has changed. All of the articles I have tested are unlimited, also the characteristics. And it worked fine until now.
I was testing some things with HikaMarket.

Hope you can help me because I don't knwo what to do now?

Hello,

I found the problem. There was a limit on the maximum pieces from an order in the article.

Excuse me for this. But the Hikashop works good.

Thanks.
