WebServerMonitor type missing in DNN 9.13.09

[carlossnts]

The following error appears in the logs after installing or upgrading to DNN version 9.13.09:

I don't know if this still exists in the DotNetNuke.dll assembly, or it should be removed with no leftover references in scheduled tasks or internal modules.

That type should be in DNN 9.13.9 (https://github.com/dnnsoftware/Dnn.Platform/blob/v9.13.9/DNN%20Platform/Library/Services/SystemHealth/WebServerMonitor.cs), it was introduced in 9.11.2 and has not been removed.

Can you look in the server logs (in Portals/_default/Logs or via the Servers page of the Persona Bar) and see if there are more details?

[carlossnts]

Couldn't find something releated in Portals/_default/Logs

In admin logs:

That is weird, it has not been removed. I suspect maybe some upgrade went wrong, if you go in bin/ folder and check the properties for DotNetNuke.dll, does it show as having the proper version?

[carlossnts]

I think it's correct

Also found this in bin/DotNetNuke.dll.config

[valadas]

That looks right to me, I must admit I have no clue here...

[carlossnts]

Do you know if there is any configuration or file for this service?

[valadas]

Not that I know of, it is pretty much in the scheduler settings that ultimately get saved in the database. The only thing that comes to mind is if this would be a multi-server instance and not all servers have been updated, is that the case?

[carlossnts]

It's a multi-server instance, and we've updated all instances. I just realized that the service is actually running flawlessly on both the development and localhost environments but not in production instance.

[valadas]

Maybe that's a clue then...

[carlossnts]

Although the development and localhost environments are copies of production after the upgrade
