We created a solution to be able to tag our customer stories in the CMS backend and then allow users to filter them through the frontend.
We created the categories through code. I had to delete one of them i.e. delete the code.
Now in the EpiServer CMS in the Admin > Content Type I am unable to delete these content types. I see a small warning icon next to 2 of them that have been deleted from the code. But when I attempt to delete them I see the message: The content type could not be deleted since it is in use.
I have tried restarting the web app based on what I have read online, but this did not help.
I would be thankful for any other suggestions.
