In regards to the logo, perhaps we could run the following query?
SELECT TOP 1000 [SettingName]
,[SettingValue]
FROM [dbo].[WebSettings]
Where SettingName like '%Logo%'
What’s listed there?
If something incorrect like just a <name>.png then need to change that to /NetPerfMon/images/<name>.png.
It would be great to track this as support case and gather diags if you could shoot me the ticket number.
