I installed 4.6.2... new domain, new database, new everything. I used the Auto install. Everything went as expected, except the Links module reports an error. I've tried uninstalling that module and reinstalling, but I get the same thing.

Error: Links 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.Links.SqlDataProvider.GetLinks(Int32 ModuleId) at DotNetNuke.Modules.Links.LinkController.GetLinks(Int32 ModuleId) at DotNetNuke.Modules.Links.Links.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

All other modules appear to be working normally. Any ideas on how I can get this module to work?

I am having the same error. I have links mod 03.03.07

Delete the trailing ; ? I do not have one in my config file for the:

<add name="SiteSqlServer" connectionString="Data Source=IPADDRESS;Initial Catalog=TABLE;User ID=USERID;Password=PASSWORD" />

I still get the same problem, with or without the ; in the web.config connection strings.
