Hi there, i have a portal installed on my host provider, the version is 4.6. the problem is that when i installed the blog module and updated it to 3.05 encounters erros, not on the update phaze thou it appears when i attempted to add it on a single page. The error comes with this message:

Error: Iss no está disponible en este momento.
DotNetNuke.Services.Exceptions.ModuleLoadException: Login failed for user ''. The user is not associated with a trusted SQL Server connection. ---> System.Data.SqlClient.SqlException: Login failed for user ''.

I tried to test all the others modules intalled on the portal and works just fine, the problem is with the blog module, already chechk my connections strings and appears to be ok and both have the same syntax and everithing. Need help please, the priority of this module is as much important as meaning everithing. thanxs.

Hi Izrael,

this exception is caused by the database denying the access to the db_user when looking for the module's stored settings. This may be caused by different problems:

  • The SQL server has been configured to operate in "Windows Authentication Mode (Windows Authentication)" and doesn't allow
    the use of SQL accounts. To solve this: change the Authentication Mode of the SQL server from "Windows Authentication Mode (Windows Authentication)" to "Mixed Mode (Windows Authentication and SQL Server Authentication)".
  • The db_users hasn't been granted correct permissions.  You need to grant dbo_owner permission to your db_user.
  • Since the error log shows that the user is trying to login with an empty username, the problem may be with impresonation (probably to be set in IIS or web.config).

Let me know if one of these tips points out you to the solution of the issue, or if you need further help.

Best regards,
Dario Rossa
