Where can I get the web server log raotation settings ?

Solution :

To check the web server log rotation settings in the dedicated server

Home » Service Configuration » Apache Configuration » Log Rotation

Here you can able to see all the logs which is related to web server . If you dont want to rotate [ every 7 days the logs will be deleted and new log will be available ] , then uncheck the boxes for those logs. If you want to remove and have only 7 days log then you can check the check boxes and click save.  In this case you will not get the old logs.
