I had timesheet gadget working on my board. it Set to show my user timesheet for 2 weeks.
At some point it stops working with error
Error in the JQL Query: Expecting a field name but got ')'. You must surround ')' in quotation marks to use it as a field name. (line 1, character 129) {}
Other strange thing is that it works with direct link /plugins/servlet/ac/timereports/timereports#!title=My+time+sheet&numOfWeeks=2&hideWeekends=true&reportingDay=1&user=557058%3A495826bb-0f0e-4ffa-b0f6-aa8a0d3906f4&pivotTableType=Timesheet&sum=day&offset=0&_=156628764133
