If there is debris on the stopper it might be preventing a good seal. Try removing the rubber stopper and wipe it off to remove any debris that might be on it. Clean out the hole that the stopper goes into as well. This will help ensure a clean seal between the hole and the stopper. Put the stopper back into the hole, making sure it is a tight fit. If it still leaks you may need to buy a new stopper.
On most push/pull stoppers the knob part that you pull on unscrews from the stopper, and under that is a slot for a screwdriver tighten or remove the stopper. On stoppers with non-removable knobs, there is a screw (usually phillips) under the stopper which can be accessed with the stopper in the up position and unscrewed to remove the stopper.
