On a clean 4.3.5 install, the system is unable to complete the portal Export Template action. It fails with the following message:

Error: Export Template is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Modules.Admin.PortalManagement.Template.SerializeFiles(XmlDocument xmlTemplate, XmlNode nodeFiles, PortalInfo objportal, String folderPath, ZipOutputStream& zipFile) at DotNetNuke.Modules.Admin.PortalManagement.Template.SerializeFolders(XmlDocument xmlTemplate, XmlNode nodeFolders, PortalInfo objportal, ZipOutputStream& zipFile) at DotNetNuke.Modules.Admin.PortalManagement.Template.cmdExport_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

It does not seem to be machine-memory-specific as it fails no matter what computer I try it from. The hosting machine has ample memory. The site itself works fine, and the export process fails even with the most plain-vanilla site (regardless whether "Include content" is checked).

Does anyone have any ideas on how to resolve this?

I'm having a different but similar problem as those listed here. I have an intranet setup with 4.3.4 and only one portal in my instance of DNN. I would like to export it and then import to a different instance. here is the error message I get...

 

Error: Export Template is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Item has already been added. Key in dictionary: '10' Key being added: '10' ---> System.ArgumentException: Item has already been added. Key in dictionary: '10' Key being added: '10' at System.Collections.Hashtable.Insert(Object key, Object nvalue, Boolean add) at System.Collections.Hashtable.Add(Object key, Object value) at DotNetNuke.Modules.Admin.PortalManagement.Template.SerializeRoles(XmlDocument xmlTemplate, XmlNode nodeRoles, PortalInfo objportal) at DotNetNuke.Modules.Admin.PortalManagement.Template.cmdExport_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

Anyone able to decript this error and point me in the right direction?

For me this WAS a DNN 3x to 4x upgrade problem, but I solved it. Here's how

Created a new 4.3.5 installation using the install.

Got WinCompare utility from SourceForge and compared the to web directories.

Concentrating on \bin, I removed ALL files in my application that WERE NOT in the new installation EXCEPT for the files used by third party modules that I had installed. Even if this is tough for you to figure out, move these DLL files out of bin, test your site and just move them back after you get errors that will tell you what DLL file is missing. In this case, it was the ICSHARP DLL and XML files that was conflicting with the newer dll of a different name in DNN 4x.
