This is a great plugin. I have set mine up at http://www.northernbeacheslocal.com.au.
I am trying however to update the logo and adding a line of body text and it is not showing. It shows perfectly in all forms of preview.
I have cleared the cache through the Chrome browser as well as downloaded WP Super Cache and followed your previous advice on how to delete the cache but still not updating on anything other than the preview.
Am I doing something wrong?
