Toilet Leak

[Sw550]

Hi guys, quick question I was hoping someone could help me with.

As the title suggests there's a problem with our toilet. Not every time, but usually every second or third time the toilet is flushed water will leak all over the floor. The water level in the bowl seems to be pretty low as well for what it's worth. I've looked and felt around but can't find or feel any leak coming from the toilet itself so assume it must be coming up from the base?

Any info on what might be causing the problem would be much appreciated.
Also if there's any way I might be able to resolve this myself that would be great, i'm overseas and my Chinese is pretty shaky

Thanks for any help!

Places to check for leaks
* the pan connector between toilet and soil pipe.
* the coupling between cistern tank and pan.
* the joint where the water inlet to the cistern connect

I would guess its the drains backing up and the leak is from the connection to the WC.
