We were deplaning the last couple of passengers (Sport team). I don't know if the APU was hooked up yet when the dirty sock smell came from the aft galley and moved throughout the cabin.  I told the Captain. He began doing some checks. There was a previous write-up on date; about the fumes. I asked the cleaners to stay off because of the fumes. All crew got off and ended up waiting in the airport for 6 hours or so because the Captain and FO did some test runs and checks. We boarded the people and the Captain became illegal. We canceled the flight. All crew had some irritations due to the fumes. I suffered a headache which lingered throughout the night. We stayed at the same hotel as our passengers. We had a 10 hour over night.[Reporter suggested] fix the problem to begin with on date.
