I believe the problem was, from which point are the cables dangling from the ceiling. But I think we can assume from the point where your light fitting is/was.
In which case there is something wrong with the way the circuit was wired. Have a check with the diagrams in the sticky thread.
The blue, red, and yellow cable is for connecting between 2 switches, it shouldn't normally go near the light. Although I have seen (and not paid too much attention too) circuits whereby both switch cables end up at the light fitting (rose or junction box) and one core is just connected through. I'll see if I can find the diagram.
Ultimately I think you need to open up the switches and note what cable/core is connected where, to each. If you can work out where they end up, it become less of a task to work out how they need to be wired at the light.

Darn, checked last week's history on this PC, no dice. May have seen it on PC at home, but in any case I think I've worked out what the diagram must have shown.
The following for interest only, as a possibility, do check out what it is you really have.
If 4 cables came into the rose or junction box at the ceiling then 2 can be accounted for as mains in, and mains out (if this is the end of the run there may not be a mains out as unlike rings one doesn't tend to feed the end back to the c/u).
Remembering that the colours are interchangeable in the following description (although obviously you have to make any changes consistent throughout
consider the following ...
3rd cable goes to one switch, 4th cable to the other.
At both switches yellow (for example) is connected to the common, blue and red to the other two connections.
Back at the rose or jb, yellow from each cable is just connected together so effectively goes from one switch common to the other.
Red (for example) on both switch cables, gets connected to the live at the rose. Blue (for example) on both cables, gets connected together and treated as the 'switched live', and taken to the lamp.
This, of course, assumes that there are cables still up in the ceiling that you are not aware of yet.
Now that may not be what you have, and I'll check the diagram (just in case that description goes bang
) I've just sketched out again, but when you check what you have at the switches, you may find that, that just might be what you started with.
Personally I'd try to rewire it more conventionally if I were you, in any case.

Well blow me down if it wasn't right here on this site after all !
