Hello Gordon,

I had similar problems on a server where I had to run nopCommerce 4.00 recently. Even after installing the .NET Core Window Server hosting runtime and the .Net Core SDK 2.1.4 I was still getting the 500.19 error when trying to run the store from IIS7.
The issue was resolved after I installed .Net Framework 4.7.1 on the server.

If you have all those installed on your machine and still getting the error you will need to enable your application stdout log. After that, you will need to run your application again and once it throws an exception you can read the exception details in the generated log files in the ~/Logs folder.

Note: You can enable the log by editing the web.config file in your nopCommerce root folder and setting stdoutLogEnabled to true.

Hope that helps!

Regards,
Anton

Hi Anton,

Thanks for the information. I have done those changes but now I'm getting the below error.

HTTP Error 500.19 - Internal Server Error

Please let me know if there is any solution for the same.

Hi Anton,

I have enabled log also but it is not writing anything to the log.

<aspNetCore requestTimeout="00:07:00" processPath=".\Nop.Web.exe" arguments="" forwardWindowsAuthToken="false" stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />

Please let me know, if I'm doing anything wrongly.

Regards
Gordon
