Hello,

I have had my site up and running for a few months now, and recently I now get a Critical error when attempting to view "settings" for any module. It seemed to have appeared randomly as I cannot match it to any changes I have made on the site. I have scoured the forums for the specific error I am getting and I cannot seem to find anything on it. I have found something close (http://local.dotnetnuke.com/Resources/Forums/tabid/795/forumid/197/threadid/389803/scope/posts/threadpage/1/Default.aspx) - but that had to do with SQL permissions, and I do not think that it pertains to this situation.

Here is my environment: Windows 7 Pro, IIS7, SQL2008 R2, .NET v4.0, DNN v05.04.04.
Third Party Modules installed: FormMaster 2008, Telerik RadControls for DNN.

Here is the error that I am getting:

InnerException: Object reference not set to an instance of an object.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: DotNetNuke.Web.UI.WebControls.TreeViewTemplate.TreeNodeDataBound
StackTrace:

Any help is much appreciated.

Thanks!

You said you have Telerik.Did you place the Telerik DLLs in there manually? Telerik DLLs come with DotNetNuke now. Perhaps you have an older version in there than DNN is expecting?

Hi all,

I tried the above suggestion by changing my web.config file:

I changed defaultProvider="RadEditorProvider" to defaultProvider="TelerikEditorProvider"

<htmlEditor defaultProvider="TelerikEditorProvider">
  <providers>
    <clear />
    <add name="FckHtmlEditorProvider" type="DotNetNuke.HtmlEditor.FckHtmlEditorProvider.FckHtmlEditorProvider, DotNetNuke.FckHtmlEditorProvider" providerPath="~/Providers/HtmlEditorProviders/Fck/" CustomConfigurationPath="~/Providers/HtmlEditorProviders/Fck/custom/FCKConfig.js" EnhancedSecurityDefault="false" SecureConfigurationPath="~/Providers/HtmlEditorProviders/Fck/custom/FCKConfigSecure.js" ImageGalleryPath="~/Providers/HtmlEditorProviders/Fck/fckimagegallery.aspx" ImageUploadPath="~/Providers/HtmlEditorProviders/Fck/fckimagegallery.aspx" ImageAllowedFileTypes="gif,png,bmp,jpg" FlashGalleryPath="~/Providers/HtmlEditorProviders/Fck/fckimagegallery.aspx" FlashUploadPath="~/Providers/HtmlEditorProviders/Fck/fckimagegallery.aspx" FlashAllowedFileTypes="fla,swf" LinksGalleryPath="~/Providers/HtmlEditorProviders/Fck/fcklinkgallery.aspx" DynamicStylesGeneratorPath="~/Providers/HtmlEditorProviders/Fck/FCKStyles.aspx" DynamicStylesCaseSensitive="true" DynamicStylesGeneratorFilter="controlpanel|filemanager|mainmenu|wizard" StaticStylesFile="~/Providers/HtmlEditorProviders/Fck/FCKeditor/fckstyles.xml" StylesDefaultMode="Static" DynamicCSSGeneratorPath="~/Providers/HtmlEditorProviders/Fck/FCKCSS.aspx" StaticCSSFile="~/Providers/HtmlEditorProviders/Fck/FCKeditor/editor/css/fck_editorarea.css" CSSDefaultMode="static" spellCheck="ieSpell" AvailableToolbarSkins="Office2003,Silver" DefaultToolbarSkin="Office2003" AvailableToolBarSets="DNNDefault,Default,NoGallery,Basic" DefaultToolbarSet="DNNDefault" DefaultImageGallerySkin="Default" DefaultFlashGallerySkin="Default" DefaultLinksGallerySkin="Default" FCKDebugMode="false" UseFCKSource="false" OptionsOpenMode="ShowModalDialog" CustomOptionsDialog="Admin" />
    <!--Upgraded by DotNetNuke.TelerikEditorProvider version 5.4.2 - Date: 8/17/2010 10:47:33 PM-->
    <!--<add name="TelerikEditorProvider" type="DotNetNuke.HtmlEditor.TelerikEditorProvider.EditorProvider, DotNetNuke.HtmlEditor.TelerikEditorProvider" providerPath="~/Providers/HtmlEditorProviders/Telerik/" toolsFile="~/Providers/HtmlEditorProviders/Telerik/Config/ToolsDefault.xml" configFile="~/Providers/HtmlEditorProviders/Telerik/Config/ConfigDefault.xml" FilterHostExtensions="True" />-->
    <add name="TelerikEditorProvider" type="DotNetNuke.HtmlEditor.TelerikEditorProvider.EditorProvider, DotNetNuke.HtmlEditor.TelerikEditorProvider" providerPath="~/Providers/HtmlEditorProviders/Telerik/" toolsFile="~/Providers/HtmlEditorProviders/Telerik/Config/ToolsDefault.xml" configFile="~/Providers/HtmlEditorProviders/Telerik/Config/ConfigDefault.xml" FilterHostExtensions="True" />
    <add name="RadEditorProvider" type="Telerik.DNN.Providers.RadEditorProvider" providerPath="~/DesktopModules/TelerikWebUI" AutoCreatePaths="true" />
  </providers>
</htmlEditor>

So far nothing has changed on the site. I am still getting the same error as shown above whenever I go to any module's settings section.
