I'm quite new to wordpress.
I just installed wordpress using MAMP today, and no matter what theme I choose, when I click to "customize" or "live preview" the theme, instead of the usual menus and things to choose from it looks like a broken page. And it's like that for all the themes. Everything else seems to be working fine, and I wasn't necessarily going to use the customize options that much, I wanted to use CSS, but I still figured I should try to figure out what's wrong with it incase it's tied to anything else I may need.
