Hello. I’ve narrowed down the problem I believe. When I write a new newsletter and the text field has Location:, on the following screen, I cannot send, nor save the newsletter. It gives me a 403 Forbidden Access to this resource on the server is denied!
Once I remove Location:, it lets me save on the following screen. The edit screen lets me save.
ie. Location: Medina gives me a forbidden error
Location Medina does not.
