I have hit a problem with this in that I am not getting a user error message when trying to create a duplicate group – although it prohibits the new group creatation – it’s just that the user remains on the first stage without any error notification.
However, I think this is because we have renamed group(s) to fandom(s) instead
What parts of your code do I need to rename from groups to fandoms to make it work 1000% correctly?
