I have run into an issue with a theme that uses the Options Framework in plug-in or theme formt, PowerPress, and Custom post types.
There is a feature in PowerPress that allows you to create a "channel podcast" for you CPT. You have the ability to select from a drop down your CPTs that are created.
When I have the theme options plug-in or have theme options activated directly in a theme the drop down appears as it should with multiple CPTs to choose from.
When I activate BCN the drop down doesn't display the CPTs any longer. Actually it does the only choice is (theme options) since that is CPT in and of itself.
Have you come across this in your development? I would like to get this figured out pretty soon, for now I am disabling the BCN because getting the podcasts our is more important than the breadcrumbs.
BTW. Yes I have removed all other plug-ins and used the 2011 theme and can repeat the issue.
