You do not need to disable third-party pop-up ad blockers on the computer you use to browse to the Metasys Site Management Portal UI in order to ensure Metasys Site Management Portal UI functionality. For previous releases, you must disable pop-up ad blockers or the Login screen may not launch. To disable pop-up ad blockers, turn off the third-party pop-up ad blocker for all sites or for the address of the Metasys system Site Director. If you cannot turn off or configure the third-party pop-up ad blocker, uninstall it from the computer.
