Well it's difficult to diagnose from a distance, but suggest you use silicone sealant on the big rubber ring that sits between the pan and cistern.
Does the toilet only leak when it's flushed? if not and its a steady drip, the leak is from elsewhere.
The cistern does not necessarily sit totally tight on the pan. Have you mounted all the parts in the correct order?
