EP stores its log file "trace.log" in the "Logs" subfolder of its installation folder e.g. c:\inetpub\wwwroot\easyprojects\logs

The log file contains details of warnings/errors, if any.

Make sure that the EP folder has the Read and Write permissions for the user the ASP.NET process is run for. Normally, it is the local "ASPNET" or 'NETWORK SERVICE" user.

You may also want to set up these permissions for "Authenticated Users".
 

For IIS 7.5, the default application pool identity is "ApplicationPoolIdentity", for such case you should set the appropriate folder permissions for the "IIS AppPool\<app pool name>" user.

NOTE. You can create the file manually.
