About global settings
Global settings enable administrators to control many aspects of OpenX operations and are available in the My Account > Global settings tab. This tab is only visible if you are working as an administrator.
Global settings are stored in the configuration file - conf.php - and you must have write permission to make any changes to the file. To avoid accidental damage, when you finish making changes in the My Account > Global Settings pages lock the configuration file again by removing the write permission for the file.
