Foreclosure, Bankruptcy and property taxes

Last year I declared bankruptcy(due to a bad loan and lemon of a home) which is now discharged so the home is in foreclosure. I got notice of Trustee Sale coming the end of the month. Now, I just received notice that I still owe back property taxes which I obviously cant afford. I thought that the bankruptcy discharged this debt, was I wrong?? I dont know what to do about paying these taxes. Also, are there any other tax issues that are going to pop up?? I am in Sacramento COunty.
