Hi. I installed DNN ok aparently, but in the home page (default.aspx) i see error messages like this:

DotNetNuke.Services.Exceptions.ModuleLoadException: Value cannot be null. Parameter name: connectionString ---> System.ArgumentNullException: Value cannot be null. Parameter name: connectionString at Microsoft.ApplicationBlocks.Data.SqlHelper.ExecuteReader(String connectionString, String spName, Object[] parameterValues) at DotNetNuke.Modules.Html.SqlDataProvider.GetHtmlText(Int32 moduleId) at DotNetNuke.Modules.Html.HtmlTextController.GetHtmlText(Int32 moduleId) at DotNetNuke.Modules.Html.HtmlModule.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

What am i doing wrong? I have already configured web.config so i don't understand what happens...Please i need help!

Thanks in advance.

Assuming your are running DNN 4 (and I believe 3.2.2 as well though I have not done an install of this version), check that you have set up BOTH the new connection string under the web.config nodes

< connectionStrings> <add name="SiteSqlServer" . . . >

AND under the legacy node < appSettings> <add key ="SiteSqlServer" value=" . . . ." >

This second connection string is needed for legacy modules including many of the core modules.

You've got something wrong with your connectionString in web.config.  You seen all the messages about things installing and upgrading when you first went to your site and didn't see any errors?

Yes, i completed both connection strings and both are the same and ok, because the DNN framework installed correctly. So i don't know what's the problem...
------
Just becuase it installed correctly does not mean both connectionStrings are correct, since the install only used the one in the <ConnectionString> section.  On the other hand if none of the core module will load then there probably is a problem with the connection string in the <AppSetting> section, since all core modules use this connectionString.  Every time I have seen this error it has been becuase of this.
