Blog Categories not Working

I've been collecting articles for the zine to put in my blog, and I placed them all in there today. everything went fine, but i have 2 other categories off of the main page that i wanted to put things in, but even when i select a category to place it in, it just keeps in on the main page with everything else. then when i actually visit the other categories, they are empty. whats this?

I've been trying to log in at the blog log in and when I log in, the log in page doesn't move, you click reload and it just stays at the log in page...
