Symptoms
When clicking the 'Compare Stats' link on the admin home page graphs, an error like the one below displays:
Server Error in '/' Application.
--------------------------------------------------------------------------------
Line 1: Incorrect syntax near '('.
Description: An unhandled exception occurred during the execution of the current web request.
Cause
This is caused by an incompatibility between version 8.0+ of the ASPDNSF software and MS SQL 2000.
Solution
Sites running version 8.0 or higher need to be using SQL 2005 or 2008. Work with your host/server admin to perform that upgrade.
