Why do I receive the message: "An error has occurred. For more information, contact your system administrator" when I am creating duplicate-detection rules, running duplicate detection, importing records, or saving data maps?
Some Microsoft Internet Explorer add-ons can interfere with creating duplicate-detection rules, running duplicate detection jobs, importing records, and saving data maps.
To see whether Internet Explorer is the cause of the error, try disabling Internet Explorer add-ons, one at a time:
On the Internet Explorer Tools menu, click Manage Add-ons, select an add-on, and then select Disable.
Retry the task that generated the error message. If you get the same error, enable the add-on that you previously disabled, and then try disabling a different add-on.
Repeat this process for all enabled add-ons until you find the one that must be disabled.
