Hello,

I have a problem with the Export Template Feature. I'm currently using Dotnetnuke 4.8.0 and I have severals sites on the same instance of DotNetnuke.

When I want to Export the Template, It work for all my site expect once. I fill in the Template Name, the description, I check(or not ) Export Content and I have always the same error :

"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.Entities.Tabs.TabController.SerializeTab(XmlDocument xmlTab, Hashtable hTabs, TabInfo objTab, PortalInfo objPortal, Boolean includeAllModules, Boolean includeContent) at DotNetNuke.Entities.Tabs.TabController.SerializeTab(XmlDocument xmlTab, Hashtable hTabs, TabInfo objTab, PortalInfo objPortal, Boolean includeContent) at DotNetNuke.Modules.Admin.PortalManagement.Template.SerializeTabs(XmlDocument xmlTemplate, XmlNode nodeTabs, PortalInfo objportal) at DotNetNuke.Modules.Admin.PortalManagement.Template.cmdExport_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---"

I tried to export some of my page manually(using the Export Page button) and it work well but I have around 90 tabs and so I don't want to export all of these manually.

Is there a way to force the export?

Thanks for your help.

I update to the 4.8.3 version and still have the same problem.

Any idea?
