The only customization I have done is for the header and I put it in the custom css section of the theme options. See below:
#branding hgroup {
margin: 0;
padding: 0;
}
So when you installed it, it posted on the homepage and on the individual posts too? I have no idea any other thing that could be blocking it then because I uninstalled all other plugins also. Could an individual post block something like this?
