When upgrading or migrating the SolarWinds Orion server, the website optimization part may fail and generate the error message:
 

Scenario 2:

During upgrade from Orion Platform 2019.4 Hotfix 5 to Orion Platform 2020.2.1
In this case, the Configuration Wizard completes fine on the Main poller without the above error, and the Orion Web Console was accessible from the Main poller URL.
But the Configuration Wizard failed with the same error above on all (4) Additional Web Servers (AWS), and the customer was unable to access the Orion Web Console from the AWS URL. The Orion Web Console throws the  following error from all AWS servers URLs,

Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed.

and the following error message in the ConfiguratonWizard.log (C:\ProgramData\SolarWinds\Logs\Orion)

ERROR OptimizeWebsite.Program - Error: Compilation failed - more information in log file
DEBUG OptimizeWebsite.Program - Error Details:
System.InvalidOperationException: Compilation failed - more information in log file
at OptimizeWebsite.WebsiteCompiler.CompileWebsite(String websiteFolder)
at OptimizeWebsite.WebsiteOptimizer.Start()
at OptimizeWebsite.Program.Main(String[] args)

Scenario 3:
Post upgrade from 2020.2.6 HF1 to 2020.2.6 HF2 , following error was noted in the OptimizeWebsite.log (C:\ProgramData\SolarWinds\Logs\Orion)on Primary main poller. Same error was not seen on Standby Main poller, which indicates an Environmental problem on the Active main poller.

Could not load file or assembly Microsoft.Web.Infrastructure Version=1.x.x.x

Orion Platform

• Custom IIS code
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\ was not cleaned up properly during the upgrade even we have a task for it that was successfully executed as per CORE-15743
• Running Antivirus on the system
• Corrupted Core installation

 

Workaround:

1. Backup the file C:\Program Files (x86)\SolarWinds\Orion\ConfigurationWizard.exe.config
2. Open C:\Program Files (x86)\SolarWinds\Orion\ConfigurationWizard.exe.config in Notepad and change the value below to "true":
   add key="DisableWebsiteOptimization" value="false"
3. Re-run the Configuration Wizard.

In the case of running Antivirus, ask them to exclude SolarWinds directories and files from the AV scanning. The list can be found on

• Files and directories to exclude from antivirus scanning for Orion Platform products (AV exceptions and exclusions).

Workaround for Scenario 3:

1. Run permission checker
2. Repair Orion Core services
