I ran in to this same problem, and here is another method to fix it:
Even though the front-end may look messed up, you should be able to log in to your WP admin dashboard still, and once logged in from the left hand menu go to the ‘Custom Content Types’->’Clear Cache’ page, and click the ‘Clear Cache’ button. Now refresh the front-end page and the content should show up normally.
Hope that helps!
