View is not loaded

Thanks fdog.
I am sure there has no error in db, anchoring,....

Below is the pseudo-code:

function A()
{
//upload file --> it works
//parse file and insert into db --> It works (All the data I need are inserted into db)

$this->load->view("viewA");//this view is existing and has content but I only get the blank page.
}

I also tried redirect to another controller instead of using load view function. It is the same :-S

Thanks,
