I’m fairly new to c# and umbraco but have ample MVC experience in other languages. I’ve been tasked to make some minor changes to an existing Umbraco 8 site and have given access to the current production site and database.
I have setup the application in IIS (10), imported the database, setup permissions for IIS_IUSRS but getting an annoying HTTP Error 500.19 which is not descriptive at all:
HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
Detailed Error Information:
Module IIS Web Core
Notification Unknown
Handler Not yet determined
Error Code 0x8007000d
Config Error
Config File \\?\D:\home\testsite\web.config
Requested URL http://localhost:8051/
Physical Path
Logon Method Not yet determined
Logon User Not yet determined
Config Source:
-1:
0:
More Information:
This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.

If I remove all content from the web.config file, the the -1 dissapears, so it appears that this is not a permissions issue that IIS cannot read the files.
Further to this, if I run the application through Visual Studio debugger, it works (albeit it says I need to run the previous build) but it does atleast run the site completely.
The only changes I made was the database credentials in the web.config, but even with the base web.config there is no difference, and as the Config Source appears to be missing I have no idea how to debug this.
Any ideas?
