Hi,

I'd look at some log4net troubleshooting to see why log4net isn't logging.

Phil Haack has an old, but still valid blog post at http://haacked.com/archive/2006/09/27/Log4Net_Troubleshooting.aspx/

The TL;DR:

First, enable internal log4net debugging: Add the following to your appSettings in web.config:

<add key="log4net.Internal.Debug" value="true"/>

Then, enable system diagnostics trace. Add  the following to your web.config:

<system.diagnostics>
  <trace autoflush="true">
  <listeners>
    <add name="textWriterTraceListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="C:\tmp\log4net.txt" /> 
  </listeners> 
 </trace> 
</system.diagnostics>

Just remember to change the path in the "initializeData" attribute.

Hi Øyvind,

I'm getting the logs in different text file. A part of the log file looks like :

I tried changing the content in CMS mode(On page edit mode) and i got an render exception, but that is not logged in the file.Can On page edit errors be logged? If so how can i  log them into the file?

I should get the log in the following format : 2017-08-08 16:33:26,034 [9] INFO LogFile: Log created now ! . What is the content that i'm getting in the above link ? 

For rendering exception, check out if you have a custom content area renderer. I seem to recall there is one in Alloy demo project and that one also has a try catch that swallows exceptions without logging them. I usually add a line to log those rendering exceptions there.  

Hi Daniel, actually I got the rendering exception to be logged in the format I  wanted it. What I need to know is how can I get the log details of the CMS errors or CMS changes. For any changes in page or blocks we can use ChangeLog in Admin mode. But for my project I need to record the Episerver CMS login details , admin mode errors if any(like accidental change of some values which cause the project to load) . I want these details to be recorded into a text file. Please suggest any method if you know. 

Thanks in advance.

This nice and useful info for me. Thanks a lot
