Questioner should make clear Q2A version that you downloaded. In this site, since development version of V1.6 is applied at any time, this site differs also in appearance and feature from stable version(V1.5.4). Although V1.6 is still under development and it is not opened, if you want to obtain the almost same thing as this site, you can download here. However, since dev version is under development, there is no security of operation. Moreover, since Q2A theme is closely related to core program's version, even if it applies theme of higher Q2A version to the stable version, it may not necessarily move correctly.
