Running WP 5.2.1 (latest version), Newsletter version is 6.0 (also latest version).
I seem to have run into a problem when trying to make a new newsletter. The steps I take are as follows:
1. Click on “Create newsletter”
2. Click on theme I want to use
3. Click on proceed to edit
When I do step 3, the result is a 404, Page Not Found error.
I had a deadline and disabled version 6, installed version 5.95 and it works.
What is going on with version 6?
