I've built a handful of e-commerce sites using Virtuemart, and its never not been a miserable experience. I spend more time trying to fix broken features (product sort ordering, trashed layouts, buggy modules, its something new every time) than actually building/managing the store. Its really difficult explaining to clients that I have such little control over their store. Even right out of the box, Virtuemart has caused me nothing but pain.
We are sorry that you experienced such problems, many times when people have stated they created many stores, we find their expectations are based on previous experience, however the new VM2 is different and therefore in some ways needs to be thought of without previous expectations and considerations. please install without anything else and play, you might be surprised. Thank you for your valued comments.
