    ‘Pregnancy %E6%80%80%E5%AD%95%E6%9C%9F%E9%97%B4’ (should be : Pregnancy 怀孕期间)

    Oh ok i too had seen that error when i visited your blog last time.
    I think the problem is wat you say.. it many not be supporting chinese characters. (well, i guess you have not misplaced any code)
    Thanks and keep blogging.

  5. hye, how to show a related post for only 1 label @ category. Let say we have a label named "English Contents", how to show only the recent posts that fall under this category.

    Please help me.tq.

  6. @ æy®
    Hi, see you can show related posts for only one category by labeling that post with that specific lable. Take your own example, if you want to display recent posts under "English Content", just label that post with English Content only.
    I hope thats the best way.
