In “Categories” box, I can’t see anything categories for choosing. It only display a announcement: “Separate multiple categories with commas”. I don’t get this problem with other wordpress blog.
Waiting for your reply!
You must type in categories before they are available to you. Type them one at a time into the box and hit Add. Then they are permanently in your list and available to choose from. You can make up any categories you like, and I don’t think it’s case-sensitive.
I added 7 categories already and 3 pots were available (with categories). Yesterday, I changed something (that I can’t remember) then I can’t see any items in Categories box anymore.
By the way, I can’t see Categories items in Blogroll Edit Link
Hahaha… I got it. I created a parent Category (with Links) and 3 sub Categories. Then, all of categories didn’t appear. After I remove this relationship, I can see all categories (without links).
