We have received feedback from one of customers when installed the nopCommerce. The following is the error message:

An error occurred while starting the application. .NET Core 4.6.26725.06 X64 v4.0.0.0 | Microsoft.AspNetCore.Hosting version 2.1.1-rtm-30846 |

When the error page is shown this means that there is some error and you need to know what the error is before fixing it. You have two options:

Open the administration by navigating to YourStoreName.com/admin and then go to System -> Log.
The Log contains all the errors and warnings in your store. Most of the time you should be looking for the most recent error. The error details contain all the information you need to investigate and fix the problem.

If you can't access the administration you have to turn on your site log, so that your errors are logged in a .txt file. To do so, modify your Web.config file by setting stdoutLogEnabled to true:

  <aspNetCore requestTimeout="00:07:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" forwardWindowsAuthToken="false"
stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" />
change to:

  <aspNetCore requestTimeout="00:07:00" processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" forwardWindowsAuthToken="false"
stdoutLogEnabled="true" stdoutLogFile=".\logs\stdout" />

Once you got the error you will get a log .txt file generated in ~/Logs folder (~/Presentation/Nop.Web/Logs for Source version of nopCommerce). 

Hope it help! In case you are looking for reliable NopCommerce hosting, please kindly give us a look.

As the Internet grows as a medium of communication, commerce and interaction, so do the prevalence of risks and security threats. One way to effectively protect your domain is with an SSL certificate. The primary reason why SSL is used is to keep sensitive information sent across the Internet encrypted so that only the intended recipient can understand it. This is important because the information you send on the Internet is passed from computer to computer to get to the destination server. Any computer in between you and the server can see your credit card numbers, usernames and passwords, and other sensitive information if it is not encrypted with an SSL certificate. When an SSL certificate is used, the information becomes unreadable to everyone except for the server you are sending the information to. This protects it from hackers and identity thieves.

In this article, i'm going to explain about how to enable SSL in nopCommerce, you will first need to purchase an SSL certificate and dedicated IP. This article assumes that you already purchase an SSL from SSL provider.

• Install SSL on your web server
• Open web.config file
• Set UseSSL value to true (<add key=”UseSSL” value=”true” /> )
• Then just save the file.

nopCommerce automatically switched to SSL when required ( for example, register, login and checkout admin ect.)

Get SharedSSLUrl from your hosting provider
Open the web.config and edit the following values

<add key=”UseSSL” value=”true” />

<add key=”SharedSSLUrl” value=”https://secure.yourhostingcompany.com/~username” />

<add key=”NonSharedSSLUrl” value=”https://secureyourhostingcompany.com/~username” />
