I’ve recently started using WordPress and when I go to “customize” to change my blog’s background colour It changes, however when I refresh my blog page to see if there is any change, there aren’t any!
Not only the colour doesn’t change, but also the font of my blog posts and my blog’s name!
Go to the dashboard Theme->Theme Options page and see what you can change there. In some themes you can change a lot for free. In some you cannot. An awful lot of themes have customizable backgrounds. To customize the fonts, however, you need a $30 a year Custom Design upgrade. Still cheaper than hosting externally at $120 a year and up.
