Proceed to Checkout Error

I have been playing with the free version of this store all day, I even watched the 1hour video on youtube which I found very helpful. The one problem I have not managed to overcome so far is a "pop up bug" that appears every time I click "proceed to checkout"

My billing address appears but no ship to address. I also get a white pop up box that appear at the top of the screen and when I click on that I can change an address. (not sure if it is the bill to or ship to)

What am I doing wrong?

Hi,
Firstly, can you give us a link to the page where you are having your issue so that we can directly test it ?

Here is a link to a test product, www.teeituptour.com/index.php/component/...oduct/1-box-of-stuff

Even you register as a new user and proceed to check out the same white box appears. Thanks for the support.

That's an issue with the CSS of your template which should use the class div.modal instead of .modal
You need to change that in the file www.teeituptour.com/templates/yoo_steam/css/bootstrap.css

Thanks for the help, I might need to find someone to help me changing the CSS.

I have also noticed that the store pages do not take changes to the joomla template settings, in other words I have the store pages changed to "contentwhite" but they still show up green.

You need to see that with your template provider.
