I had disabled Custom Press for a short time and once re-enabled the custom post types ("Plants") aren't opening to their specific pages. They are being redirected to the homepage. I had something similar happen before as well.
http://tamanasprings.com/plants/ is the main page to view the custom posts listings, or through the back end.
EDIT: This is my previous post, though no solution was needed then as they started loading. I'm not sure what's causing this issue. https://premium.wpmudev.org/forums/topic/custom-press-posts-no-longer-loading
Hope you guys are able to help figure this out.
