Object reference not set to an instance of an object.

Hi guys,

After a long couple of days my brain is close to shutting down.

Just upgraded from V3 - V4.0.2.1 & am having this Object Reference error occur with the below stack trace.

This may be a simple fix but my head is about to implode. - Appreciate any help. :)

<table border="0" cellspacing="0" cellpadding="0" align="center"> <tbody><tr> <td style="padding: 0pt 9pt;" align="left" valign="top"><pre>[NullReferenceException: Object reference not set to an instance of an object.]</pre> <pre> TidyNet.Clean.CleanNode(Lexer lexer, Node node) +493</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +61</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +39</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +39</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +39</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +39</pre> <pre> TidyNet.Clean.CreateStyleProperties(Lexer lexer, Node node) +39</pre> <pre> TidyNet.Clean.CleanTree(Lexer lexer, Node doc) +23</pre> <pre> TidyNet.Tidy.ParseInternal(Stream input, String file, Stream Output, TidyMessageCollection messages) +534</pre> <pre> TidyNet.Tidy.Parse(Stream input, Stream output, TidyMessageCollection messages) +41</pre> <pre> umbraco.cms.helpers.xhtml.TidyHtml(String html) +372</pre> <pre> umbraco.library.Tidy(String StringToTidy, Boolean LiveEditing) +5</pre> <pre> umbraco.editorControls.tinyMCE3.TinyMCE.Save() +219</pre> <pre> umbraco.controls.ContentControl.saveClick(Object Sender, ImageClickEventArgs e) +91</pre> <pre> umbraco.controls.ContentControl.savePublish(Object Sender, ImageClickEventArgs e) +19</pre> <pre> System.Web.UI.WebControls.ImageButton.OnClick(ImageClickEventArgs e) +108</pre> <pre> System.Web.UI.WebControls.ImageButton.RaisePostBackEvent(String eventArgument) +118</pre> <pre> System.Web.UI.WebControls.ImageButton.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10</pre> <pre> System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13</pre> <pre> System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36</pre> </td> </tr> </tbody> </table> </div> 

Thanks Guys :)

Ok that formatting didn't work out - try again :(

This should be better

The error only appears on publish of certain pages, but the site works fine - I just can't publish updates,

I feel its an issue with datatypes but can't seem to find the culprit.

Any other suggestions?

Do you use any special datatypes or any other thing that isn't default in umbraco? Looks like there's something that is compatible with v3, but isn't with v4

The odd thing there is I have two home pages in this umbraco installation for different sites based on the same nodelist & doctypes. One works, but the other throws up this error.

*scratches head*

I'll dive back in & see what other evidence I can pick out.
