Unexpected website error when opening the Orion Web Console

Overview

The following errors are displayed when opening the Orion Web Console:

Unexpected Website Error
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET\root\6faafa1c\92094bad
\App_Web-orionmasterpage.master.b6031896.lqrhb0id.0.cs(305): error CS0433: the type 'Orion-Contriols_PageHeader' exists in both
'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET\root\6faafa1c\92094bad\App_Web_otu5ty5l.dll' and
'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET\root\6faafa1c\92094bad\App_Web_dz0dqaye.dll'

 

A similar error may appear, such as the following:

[A]ProfileCommon cannot be cast to [B]ProfileCommon. Type A originates from 'App_Code.evlgtu2d, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\6faafa1c\92094bad\App_Code.evlgtu2d.dll'. Type B originates from 'App_Code.n3gqie9e, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\6faafa1c\92094bad\App_Code.n3gqie9e.dll'.

Environment

All NPM versions

Cause

This can occur when setting up the precompiled website. Deleting these temp files forces it to rebuild.

Resolution

Note: Save a copy of the original Temporary ASP.NET files to your local drive as a backup file, in case you need to roll back later.

  1. Stop the SolarWinds Information Service (SWIS) and the World Wide Web Publishing Service from Services.msc if Orion is the only website running on the server.
  2. Delete all files and subfolders from c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\
  3. Restart SWIS and World Wide Web Publishing Service.
  4. Go to Start > All Programs > SolarWinds Orion  > Configuration and Auto Discovery and run the Configuration Wizard.
  5. Select all three options and follow the prompts to finish the wizard.
    Note: Do not skip website optimization.

If the issue is not resolved, Rebuild the Orion Web Console using advanced repair.
