Melted connection in the light fixture

The light fixture failed in a spectacular manner. See the disaster:

I am scared to connect it again. My house has old wiring with old fuses no RCD.

What could possibly have caused that?
It’s the lighting circuit so may not be that risky but I would like to know what you think.
