I have asked a lot of people but nobody knows how to fix this problem.

Hi, this is a new installation,  XP, SQL Server 2005. The installation completed successfully but at the end when it was supposed to transfer me to the web page, it gave me an error: VALUE CAN NOT BE NULL PARAMETER NAME= VALUE

I reset the IIS connection and put a new version of the web.config, as suggested by someone, without results. I also tried what other person said about adding a space at the end of a line on the web.config and try again but I tried also that without results.

If anyone knows how to solve this, please help me. I need this to be solved as soon as possible, so any help will be appreciated.

Thanks in advance.

Lissy

  • are you trying to install DNN 4.8.0 or a previous version?
  • What is the site name?
  • are there other values that might cause issues due to a blank or special characters?

if the install fails, I strongly suggest to start again from scratch.

Hi. Thanks for answering.

I installed DNN version 4.08. It is a new site. You can not access the site yet, since I have not installed it. I am new in DNN so I do not know where to look for to find if there are blank or speci

The server name is PRT-HQMJ8F1, the database name is dotnetnukenew. The web.config (connection string) is this one:

 

<

<!--

<add name="SiteSqlServer" connectionString="Data Source=*********;User ID=******;Password=******" providerName="System.Data.SqlClient"

<!--

<

connectionStrings> Connection String for SQL Server 2005 Express--> Connection String for SQL Server 2000/2005 -->add

 

name="SiteSqlServer"

 

connectionString="Server=*******;Database=DotNetNukenew;uid=******;pwd=*******;"

 

</

<!--

<add key="SiteSqlServer" value="Data Source=PRT-HQMJ8F1;User ID=lissylopez7;Password=godnow"

I edited your post to remove your servername, username, and password from the connection strings (not a good idea to post those on an open forum).

Did you install the Active Directory provider when you went through the wizard? If you did then comment all instances of <add name="Authentication"... /> under the <httpModules> section in your web.config and see if that makes a difference. There's a bug that with the provider that showed up after the release of 4.8.0 and while the error message you're seeing isn't the same as the one that usually shows up it is similar and I can see that the provider is showing up in the Stack Trace.

Hi, I edited the web.config and put in comments the authentication. It was only one line of the code.

I am getting now a different error:    An unhandled error has occurred.

The address said:    http://localhost/DotNetNuke/Default.aspx?tabid=36&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0

What else should I check?
