I had things working fine with DNN 4.9.0 at www.VashonGreen.org, and then just upgraded to DNN 5.1.1.

[After I do any DNN upgrade, I typically update any modules to the latest version, so presume when I went to DNN 4.9.0 about 9/18/08 that I would have updated to the latest Blog module. I downloaded Blog versions v3.04.00 on 1/22/08, v3.05.00 on 11/8/09, and v3.95.01 on 7/18/09, so likely had that as my update path.]

Anyway, as you can see from my site, I'm now getting the following error  in the area that displays a summary of the most recent blog entries, both at www.VashonGreen.org and any other blog display page, e.g., http://vashongreen.org/Blogs.aspx:

An error has occurred.
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.NavigationControl.SolpartMenuNavigationProvider.Bind(DNNNodeCollection objNodes) at DotNetNuke.UI.WebControls.SolPartActions.BindMenu(DNNNodeCollection objNodes) at DotNetNuke.UI.WebControls.SolPartActions.BindMenu() at DotNetNuke.UI.WebControls.SolPartActions.Page_PreRender(Object sender, EventArgs e) --- End of inner exception stack trace ---

I know DNN switched from SolpartMenuNavigationProvider to DNNDropDownNavigationProvider(?), but am unsure if the depency on the outdated SolpartMenuNavigationProvider is in your code or the core code (or mine- though I haven't written custom code, just custom skins for this site).

Any suggestions?

Hi,

I wondered if there was actually a resolution to this as I am experiencing the same problem.

I am reasonably new to DotNetNuke, and I didnt really understand one of the possible resolutions provided shown below...

After upgrading to DNN5, be sure to include the ProviderName attribute into the dnn:ACTION control of your containers:

<dnn:ACTIONSrunat="server"ID="dnnACTIONS"ProviderName="DNNMenuNavigationProvider"/>
