7.7.2 New installation throws a server error 500.
I have followed the instructions to the letter for installing Umbraco manually.
But, no matter what I do, I cannot get past this error. I have installed 10 or so Umbraco sites in the past, and I have never had this much of a problem.
It is on Windows Server 2012 R2 Standard with IIS 8.5.
I have double-checked everything; the permissions, the app pools, the web.config.
I have a SQL Server 2016 database on there, but I don’t think it is getting that far.
Any help would be tremendously appreciated. My sanity is at stake.
Update: I finally got Umbraco to function on the website. The problem was twofold. First, the web.config file had sections in it that were configured as locked at a higher level, thus causing the error 500.19.
Below are the steps to resolve:
1.Go to C:\Windows\System32\inetsrv\config\applicationHost.config and open in notepad
2.Change the following key value present in
<section name="handlers" overrideModeDefault="Deny" />
change this value from “Deny” to “Allow”
<section name="modules" allowDefinition="MachineToApplication" overrideModeDefault="Deny" /> change this value from “Deny” to “Allow”
Then, I began receiving HTTP Error 500.22 - Internal Server Error An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
This error implies that the application can only run in Classic mode in the Application Pool. Not true of the Umbraco application.
So, In the <system.webServer> section of the web.config file, I had to add the key <validation validateIntegratedModeConfiguration="false"/>.
Now Umbraco runs perfectly in on the server.
But, alas, my Filemaker Server Administrator application is still throwing an error 500. I will update this if I can fix it.
