I am trying to export a portal and it fails immediately. I have successfully exported other portals in this install, but the one I want does not work. 

Here is the error I am getting. 

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: An error occurred while parsing EntityName. Line 1, position 7. ---> System.Xml.XmlException: An error occurred while parsing EntityName. Line 1, position 7. at System.Xml.XmlTextReaderImpl.Throw(Exception e) at System.Xml.XmlTextReaderImpl.ParseEntityName() at System.Xml.XmlTextReaderImpl.ParseEntityReference() at System.Xml.XmlTextReaderImpl.Read() at System.Xml.XmlLoader.ParsePartialContent(XmlNode parentNode, String innerxmltext, XmlNodeType nt) at System.Xml.XmlLoader.LoadInnerXmlElement(XmlElement node, String innerxmltext) at DotNetNuke.Entities.Tabs.TabController.SerializeTab(XmlDocument xmlTab, Hashtable hTabs, TabInfo objTab, PortalInfo objPortal, Boolean includeContent) at DotNetNuke.Modules.Admin.Portals.Template.SerializeTabs(XmlWriter writer, PortalInfo objportal) at DotNetNuke.Modules.Admin.Portals.Template.cmdExport_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

looking at the export file, here is the last line. 

<content type="DNNHTML" version="05.06.03"><![CDATA[&lt;htmltext&gt;&lt;content&gt;&lt;![CDATA[&amp;lt;p&amp;gt;&amp;amp;#160;&amp;lt;/p&amp;gt;
&amp;lt;p&amp;gt;&amp;lt;span style=&amp;quot;font-size: large&amp;quot;&amp;gt;&amp;lt;span style=&amp;quot;font-family: Times New Roman&amp;quot;&amp;gt;&

Any help would be greatly appreciated. 

We are running 5.6.2. On a test server we have upgraded to 6.2 and have the same problem.

The template file has 14,782 lines in it. And the XML tags are not complete. It all most appears the file is getting too big and DNN cannot handle it.
