Custom Post Type Won’t Save

Hello
First of let me thank you for a great plugin.
Truly one of a kind.

Now to the problem.
A site we are working on requires custom post types for its members which we need to geolocate on the map. Novomaps fitted the requirements perfectly.
To add the Novomap fields to the custom post I updated the
$screens = array( ‘post’, ‘page’, ‘OUR_members’ );
The map shows up at the bottom of the post, but we go to save it, we get a white screen with a message “This is no Post or Page.”

Do you know if there is another place I need to add the Custom Post type name for it to work properly?
Or I shouldn’t mangle with the code, and you are working on an option for the users to apply the plugin to page, posts, custom post types based on text field in the admin panel?

Thank you for our time and help
Best regards
Ivan
