I’ve submitted this as an issue on Github. On a fresh 9.0.1 install using the Atomik theme, I am getting an error when trying to add a new express entry. I’ve attached a screenshot of what I’m getting.
Running on PHP 7.4.25.
I created a new express entity with various types of attributes. Had no problem there, but then when I go to add an entry, I get an undefined method error.
The Atomik theme comes with a couple express entities, and the add entry forms works just fine for those.
It seems that when trying to add new express entries, the forms aren’t being found for user-created entities.
