SOUNDS like u have put a live to neutral across the switch
and caused a dead short.

All 4 reds go in a block together. These do not get fitted to either of the wires on the light fitting. Look for a block labelled loop in the ceiling rose and put them here.

The three black wires that were together will be the neutral. Wire these into the terminal that will connect to the blue neutral wire of the light fitting.

The remaining black wire is the switched live. Technically this should have a red sleeve or bit tape on it to indicate that its not a neutral but its often fallen off or was never put on. Wire this to the terminal that has the brown live wire of the fitting connected to it.

Hopefully you will have a 4th block that you can use for any earth wires too.
