    make sure the float is at the right height to cut off water when filled

    It may be the seal on the bottom of the tank.

    In my case, when it wasn't the flapper it was the fill valve.

      You're welcome. If your toilet is more than 5 years old, it is quite possible that's the problem. I've changed them on 2 toilets, not too difficult. BTW, I found it easier to reuse the "shank" that was still on the toilet rather, than drain the tank...FYI just in case yours will fit with the new valve.
      I also had everything go to black goo after putting bleach in the tank, and also another time when using tank tablets...Stay away from both.

    Check to make sure the water cut off valve is set to cut off the water flow a little before the water height starts pouring back into the tube. Also, it the water is still flowing into the bowl, (you'll see water movement in the bowl after it fills) you may need to adjust the flapper a little up , down , or make sure it is sealing as it should.

    Thanks so much for taking time to answer my question. I was thinking that was my last option before replacing the whole toilet! Thanks again!

    Thanks for taking the time to answer my question. May you know the answer to this. Is there supposed to be a seal the flapper sits on or just rest on the hole in the bowl? Thanks again

    It's supposed to sit on a seat which is sealed to the hole. See attached picture.

    Try to make sure that the chain is just right so that when you pull the handle it will lift the flapper right away. My toilet leaks on and off after replacing the flapper. I couldn't figure out until I adjusted my chain.
