I've been having a lot of issues uploading images, so I thought I would try v5.2. Now the editor won't render:
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I am running in a medium trust hosted environment (godaddy) which hasn't been a problem since I used v5.1.
Any ideas?
