Hello,

recently my host has changed the security level of the .NET environment to 'Medium Trust' as a mean to address security concerns. After that, I can't upload/install any new module, skin or container to my DNN. I always get this error message:

DotNetNuke.Services.Exceptions.ModuleLoadException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. ---> System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet) at System.Security.CodeAccessPermission.Demand() at System.IO.Directory.InternalCreateDirectory(String fullPath, String path, DirectorySecurity dirSecurity) at System.IO.Directory.CreateDirectory(String path, DirectorySecurity directorySecurity) at DotNetNuke.UI.Skins.SkinController.UploadSkin(String RootPath, String SkinRoot, String SkinName, Stream objInputStream) at DotNetNuke.Modules.Admin.FileSystem.WebUpload.cmdAdd_Click(Object sender, EventArgs e) The action that failed was: Demand The type of the first permission that failed was: System.Security.Permissions.FileIOPermission The Zone of the assembly that failed was: MyComputer --- End of inner exception stack trace ---

It seems that DNN needs a permission to write files somewhere and the system doensn't allow it. But, for what type of permmision should I ask to my host exactly?

Can anyone help me with this?

Thank you

Fernando

Hello again,

I forgot to say that it is a DNN 4.3.5 install. Also I can upload files through "file manager" and rest of things seems to work fine.

Thank you

Fernando

Hi Jeff,

No. I couldn't get any help from my ISP so I'm very busy rebuilding my site in a new hosting plan with a new provider (WebSecureStores). It is a fresh install 4.3.7 (provided by them) and things go fine.
