This is a wonderful theme according to its own webpage. And it loooks much better than other themes and have a lot of customizable functions. However, this error makes it unusable.
I checked it again, in the Theme Option page, the function of Layouts, Grid Loop and Post formats are all not functional. What ever you choose to customize something in this three tabs, nothing happened, they simply go back to the first choice and stay there.
Please can anyone answer the question?
