If you are seeing an error message that looks like this, you are being affected by a bug in Blackboard and your Grade Center will need to be reset.

errorParsingDataMsg
TypeError: 'undefined' is not an object

or

errorParsingDataMsg
TypeError: Unable to set value of the property 'allowContentEdit': object is null or undefined

To fix:

NOTE:  You MUST use Mozilla Firefox as your browser - Safari, IE and Chrome do NOT work for this fix.

While in your Grade Center hover over Manage and go to Column Organization.  From there, move the placement of any one of your columns.  Then, click Submit.

NOTE:  You may have to do this TWICE to get your grade center to reset properly.
