Hi,

I just finished installing DNN 4.3.6 afresh into a new folder. I made the following changes to web.config.

1. ConnectionStrings:

2. AppSettings

 I saw two separate entries: one for MS SQL Server 2005 Express and other for SQL Server 2005 / 2000.

I only gave the data for the second entry in both sections: for SQL Server 2005 / 2000. I removed the first entry for SQL Server 2005 Express.

I was able open the site and login; but all modules show ERRORs Here is one example:

Welcome To DotNetNuke Module:
==========================
Error: Welcome To DotNetNuke® is currently unavailable.
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 ---

Later, I went to Host>>Host Settings; changed the site name and home URL, set the SMTP server; when I clicked the UPDATE link, I got the following Error.

DotNetNuke Upgrade Error

The Assembly Version ( [ASSEMBLYVERSION] ) does not match the Database Version ( [DATABASEVERSION] )

ERROR: Could not connect to database.

The type initializer for 'DotNetNuke.Data.DataProvider' threw an exception.

Please help me understand and resolve this problem.

Thanks a lot in advance!
