    Unable to publish

     

    So, this is what happened...

     

    I did some R&D with the API and I added a method in my XSLT Extension, just to test the Publish method

     

            public static string testPublish(string nodeName)

            {

                try

                {

                    DocumentType dt = DocumentType.GetByAlias("textpage");

                    User author = User.GetUser(0);

                    Document doc = Document.MakeNew(nodeName, dt, author, 1049);

                    doc.Publish(author);

                    umbraco.library.UpdateDocumentCache(doc.Id);

                }

                catch (Exception e)

                {

     

                    return "something went wrong with the node! Exeption thrown" + "<br/>" + e.Message.ToString();

                }

                return "Document Published!";

            }

    The thing is that after I created some nodes that were working just fine (I could see them in my menu, etc) I went back to the backend and suddenly I could't publish any nodes. And I got this error

    I edited the web.config to restart the application, I did the whole iisreset routine and still I couldn't publish. So I went to the umbracoLog to check things out. So there are my findings:

     

    Entry 2992: Loading content from database...

     

    Entry: 2993: NodeId: -1

    After a search in the API and careful reading of the umbracoLog here is the entry which I believe shows where the problem is

    Xml wasn't saved: System.Xml.XmlException: Invalid XML document. The document does not have a root element.
       at System.Xml.XmlDocument.Save(String filename)
       at umbraco.content.PersistXmlToFile(XmlDocument xmlDoc)

    Just noticed that the umbraco.config file keeps disappearing when I try to republish the entire site or just a node. As a result I get the /config/splashes/noNodes.aspx when I run the site.

    Did I say that today I updated to 4.5.1 ? Then the problems started. Everyone else has downloaded and tested 4.5.1 ? Maybe it's a general problem. Or not... :(

    SOLVED IT!

    After a lot of hours under the umbraco hood I found the problem...

    oh... and the problem was so insignificant that I might be a little dumb. because it was right in front of me.

    Well, apparently I created a document type with a greek name and forgot to change the alias to an english one, as a result, an empty alias for the document type. That messed up the DTD of the umbraco.config xml... and all hell broke loose.

    I guess umbraco shouldn't let you save a doctype with an empty alias... and I guess I should report the bug to the team.

    Hi Bill

    I have run into the same error as you it seems. I have imported some 1000 documents programatically and after they have been imported it seems this issue has occured whenever I try to publish a node or restart the app and so forth. I have checked all my doctypes and they all have an english alias - no funny characters!

    I'm running 4.5.1 as I guess you did. Any other findings you might want to share from your issue-solving actions?

    Thanks a lot in advance :)

    Kim
