Hi Scott,

I'm having a very annoying error and don't know how to fix it. This happens when I add users to a role and does not happen when I remove users from a role. As a result, the action is still completed, but the notification email is not sent.

InnerException: String reference not set to an instance of a String. Parameter name: name
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Globalization.CultureInfo..ctor
StackTrace:
Message: DotNetNuke.Services.Exceptions.ModuleLoadException: String reference not set to an instance of a String. Parameter name: name ---> System.ArgumentNullException: String reference not set to an instance of a String. Parameter name: name at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride) at DotNetNuke.Security.Roles.RoleController.SendNotification(UserInfo objUser, RoleInfo objRole, PortalSettings PortalSettings, String Action) at DotNetNuke.Security.Roles.RoleController.AddUserRole(UserInfo objUser, RoleInfo objRole, PortalSettings PortalSettings, DateTime effDate, DateTime expDate, Int32 userId, Boolean notifyUser) at DotNetNuke.Modules.Admin.Security.SecurityRoles.cmdAdd_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

DNN 4.8.0

Happens with both English and Other localizations.

Each time this occurs, it restarts the application. This is REALLY annoying.

Can you help me troubleshoot the problem?

Thanks

Thanks a thousand Scott! This explains and solves everything. The problem comes from a custom module on my site.

Best regards.

Hello

I have the same problem. And I have my own module(s) installed. With new own profile properties added. Please can you tell me how did you solved this problem. Need I call something while adding and registering new user? How can I initialize user profile by application module logic?

Thanks

Alex
