I can’t change my blog address. I checked the instructions in http://en.support.wordpress.com/changing-blog-address/. But when I move the cursor over that address, it only shows “leave blog”. I tried to register two other blogs and their addresses can be changed as showed in the instruction. Why?
However, some wired things happened that I can’t remove some posts of the blog, the blog is migrated/imported from my previous self-host wordpress blog. I don’t know whether that has anything to do w/ it.
