I have a newly installed SolidCP 1.4.6 with the web.config patch in place to fix the websites stuff. Everything else is working, its an all-on-one server install, so IIS, MSSQL, etc are all local. I installed Simple DNS Plus v6.0 (Build 125) and that is working fine on its own. I did the sdnsape-setup.exe thing, got the HTTP API working and can browse to the status (e.g. http://127.0.0.1:9753/status?format=html ) so I know its working and usern/passw works.

But SolidCP is throwing errors that seem to me like its incompatible or somehow there is a version mismatch.

When I try to Import zones to a Space, I click to expand the DNS node and nothing happens in the UI, but Windows Event Log shows this:

[8/1/2020 9:37:56 AM] ERROR: 'SimpleDNS Plus 6.x' GetZones
System.FormatException: Input string was not in a correct format.

If I try to add a zone, I do get an error in the SCP UI (note, the domain was made up and does not exist) and an error in Win Events:

Any ideas on something I might have missed? Or how to test and fix; a way forward? Thanks - Jeremy
