Hi there,
Thank you for reaching out to us!
In general, Events follow the same user roles and permissions as any other default post in WordPress. If you remove editing and publishing permissions for Editors in Posts, the same will be true in Events.
If you want to change the permissions on your site so that Editors can only edit and publish events to your blog but no Posts (or vice versa), please read the following article for more information on how to accomplish this:
Editing User Roles and Permissions
I hope this helps! If you have any other questions at all please feel free to let me know and I’d be happy to help as best I can!
Cheers,
Patricia
