@grappler I'm milestoning this for our larger 2.0.0 release and will look to get it resolved then, thanks again for the feedback!

[jeffpaul]

@grappler I'm no longer seeing this PHP notice. Are you still seeing it? If so, can you confirm your WordPress, Distributor, and PHP versions?

[grappler]

@jeffpaul You can force the issue by including add_filter( 'dt_available_pull_post_types', '__return_empty_array' );

@grappler Thanks for the additional information here. I've been able to reproduce this and have a fix in place in #703
