Broken Theme Previews in WordPress 2.6
Posted July 22, 2008 by Mister Knowitall
I created a theme for WordPress, but in 2.6 the theme previews window is empty when I select it. Why is it doing that?
ANSWER: The same thing happened to me when I was designing the CSS Magic SEO theme that this site uses. I discovered that the theme previews mechanism doesn’t work if your theme folder has a space in the name.
Without more information, I can’t be sure this answer fixes things for you, but those blank theme previews filled in when I removed spaces from my theme folder names.
