Select which object to log and which are not.
Allow logging for limited objects on your site.
Go to Joomla => Components => PayPlans => Configuration.
Click on the Expert pane.
Block Logging parameter allows you to mention the objects which needs to be blocked for logging. That mean no logs will be created for the mentioned objects.
For eg. setting Plan in Block Logging parameter will not create logs for any changes related to Plans.
Thats how you can set different objects in this parameter to block the related logs.
