I today purchased the template with the intention to used it for a website I am developing.
I did a test install with sample data and then the template looks the way it is supposed to. However on the site I am developing (which will become the live site) the way the template looks is totally different, larger pixels in the menu bar, buttons too large, search field which looks bizar etc..

Can you have a look and see what is causing this strange behavior?

Both sites can be accessed via
http://www.webmatix.be/testsite -- with the sample data and
http://www.webmatix.be/mmj -- with the purchased template installed

The testsite is offline but can be accessed via user support pw markeheim
