Ummm…. actually, it looks like you do have a filter to exclude custom post types. 🙂
Just add this to your functions.php
// Suppress the editorial calendar for a custom post type.
add_filter('edcal_show_calendar_{your-post-type}', function() { return false; });
You can see the filter is applied in line 124 of edcal.php
I had this same problem while pulling our production database to my dev environment.
I changed the API key to pull from http instead of https, and it worked.
Sweeeeeet! – That worked. Thanks Pär!
Made a small donation. Keep up the good work! 🙂
