When logged in as the student account (username "student") to the Mount Orange School site, I am seeing an error when accessing the Calendar (User menu > Calendar):

Exception - Unsupported operand types: int - stringMore information about this error

• - - - - - - - - - - -

Also, when attempting to add the 'Calendar' block to the Dashboard page, another error is given:

Exception - Unsupported operand types: int - string

... and then it isn't possible to access the dashboard at all without receiving the same error above.
