I've followed a tutorial online on how to make my own Wordpress theme. I've kept it very basic.
I installed Powerpress and it doesn't work with my theme. I'm just trying the shortcode [powerpress url=""] at the moment simply to see if this would work. I switched over to Twenty Eleven just to check if the plugin works and it works fine, but not with my custom theme.
I went to Settings > Media Appearance and selected "Yes, please try to fix" to "Having Theme Issues." I cleared my browser cache and WP Super Cache just to be sure.
Since this is my first crack at creating a Wordpress theme - and remember, I'm keeping it simple - I'm not sure if I'm missing something in the code that Powerpress depends on.
