I have an error when I try to add a new collection. I am logged in as Host.

The error message is: Request for the permission of type System.Security.Permissions.SecurityPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed

And the message in my DNN event log is:
