I have upgraded and migrated my webportal, with the following:

  1. upgrade from 5.6.5 to 6.0.2
  2. SQL from Express edition to Web edition
  3. Windows from 2008 Standard and 2008 R2 Standard
  4. IIS 7.0 to IIS 7.5

the upgrade went smooth but with some module upgrade errors but i resolved them manually later.

Every time I install a new module, the module installs correctly but after I refresh the page i get an error.

It is usually resolved either by the IIS and MS SQL server restart and on rare occasions a page refresh.

Server Error in '/' Application.

From the stack trace it would appear that the error is specific to a new instance of a custom module being placed on a page:

Hyper.Modules.Settings.Controller.GetSettings(Int32 ModuleID) +534

and results when reading settings values from the database - most likely due to there being no rows of settings data for this particular ModuleId when the module is first placed on a page.

However, you mentioned that the error occurs when a module is installed. Do you mean when using the Host-->Extensions, Install Extension Wizard? If so, does the error occur when installing a module from the DNN Forge - for example the Links or Events or other modules?

Thanks for your reply and pointing out that particular reference.

I had previous small issues with this third party module (purchased from snowcovered)

Indeed when any module I install from codeplex.

I will follow the matter with this developer of the module
