I have a problem in our production environment when I try to create new folders.
The problem shows both when creating folders in block gadget and in Media gadget.
The request shows normal:
Content of the Post to ".../cms/Stores/contentdata/"
I can see that the request accept shows application/json as it should
But it returns 406 Not acceptable.
It works fully in test environments
Creating pages (that uses the same kind of requests) it works fine in production environment.
Uploading files in existing folders works fine.
I have full admin/edit rights.
Version is Episerver CMS 7.18
Anyone have any idea what the problem is?
