Help! Logs!

Hello experts,

I am not so familiar with logs and log file, so I decided to ask you.

I created an order (bought a computer and the payment status is "paid") and I got this log for the activity -> http://prntscr.com/hds1jo

Is it normal or it should not be like that. I apologize for my misunderstanding.

One more question is about If I want to write to, I assume I need to use ILogger/DefaultLogger, am I right? Can someone explain me how can I use it and where in the solution, examples will be much appreciated. Thanks in advance!

Best regards!

Anyone, who can help or I am alone, playing with the logs?

As per the error message, you have a problem with email.  Go to the email configuration and "Test" it there to see what happens.

To use logging in your own classes (plugins), just inject ILogger.
You can see an example in \Plugins\Nop.Plugin.ExchangeRate.EcbExchange\EcbExchangeRateProvider.cs
