Juraj, I have checked that directory and there is nothing in it except something called
MaxMind/GeoLiteCity.dat. No other log files. As for the permissions, I have given the process sufficient permission to write to the WebAnalytics folder.
I have run the
Process analytics logs task manually many times without any relevant errors in the Scheduled Task app or in the Event Log app.
Web farms are not used.
I also checked the database table
Analytics_Statistics and there are no records at all.
