The Websphere protal 6.1 was logging normally
[WAS_HOME]\profiles[PROFILE_NAME]\logs[SERVER_NAME]\
But when I tried to clear the content of the log file to clear old logs, WebSphere log to this file anymore and the file is always blank, knowing that i cleared the content of the old log file and didn't remove the the file itself so i don't think it would be a permission problem.
Thanks

You might want to cross check the configuration in WAS admin console whether if it is mapped to the proper location as expected. Because the scenario of yours works fine with my environment.
