I wan't to report some bugs

Let me start of by saying that I love this design and it is very relevant for my next website idea. I can however not buy it before some basic bugs have been fixed.

These are bugs found on your demo of Hot Cosmetics:

1. In the upper right corner the buttons "Register" "Sign In" and "My Account" are dead.
2. Adding a product to the cart, then removing it results in a "blank screen" meaning no contents between header and footer. This should show an empty cart instead.
3. Entering a coupon code results in "blank screen"
4. Updating the quantity of an item results in "blank screen"
5. When choosing credit card as payment a validation should take place. Right now its possible to continue without entering anything in credit card. And no matter what it is possible to place an order before payment, thats not right in my opinion.
6. Registering was hard because when registering during checkout a blank screen once again appears. I found out that the registration does take place even though the previously mentioned buttons in the right corner does not change. This also means its impossible to log out again.

that is demo, some things are put there only to visualize idea and are not connected to anything, so that are not bugs .

To everybody wondering about this Ivan is right. I went ahead and bought the template. I used the "HotStart" installer and I did not experience any of the problems from the online demo. All buttons working and no blank screens.

Why Ivan the the team thinks its a good idea to present the demo this way I don't know, but these specific problems are not something to worry about.

We disable several Joomla and VirtueMart features on demo intentionally. There are many reasons for that. One of the most important is to protect demo server from spammers. Also, we disallow making user accounts on demo sites and contacting us through demo sites.
