I am having some trouble with sending marketing emails after updating to 9.6.7 from 9.4.11.
We have 3 sites under our solution and we can send an email from one of them but not the other two.
When previewing the email under the content tree it looks correct but when previewing in the marketing part, it gives us an error "No layout selected for website".
I already checked the website settings and a template is set for all websites, also for the email (page and paragraph).
Can you give me any tips on what mistmatch to look for?
