Resolution

This is usually caused by having the Compatibility level set too low for your database. To fix it, in SQL Server Management Studio:

  1. Connect to the appropriate instance.
  2. Expand Databases
  3. Right-click the “FogBugz” database and select ‘Properties’
  4. Go to ‘Option’
  5. There should be a compatibility mode dropdown there; select the highest available (100 for SQL 2008, 90 for 2005).
  6. Click OK

There is zero downtime involved in the change; it only changes how SQL Server interacts with the database and doesn’t change the database itself.
