Old wiring to new ceiling rose

    I have a new ceiling rose with two ports - blue and brown.
    The wires from my ceiling are black, red (several reds twisted together), green, and a black with a brown sleeve.
    We cannot seem to get the light fitted. The bulb will light up but the wall switch won't turn it off - it stays on permanently.
    The switch at the wall also now feels like it won't press down all the way.
    My two questions are:
    - Which wires should be connected from the ceiling to the light?
    - Does this sound like a switch issue - would the switch also need replacing?
    Any advice would be greatly appreciated.

    Photos please: preferably of the wiring before you started as well as how it is now.

    So how was your old ceiling rose wired, did you not take a photo, can you remember what was there, where did all the twisted red wires terminate. Post a photo of what you have got

    Black wires in to the Blue Neutral Terminals
    Black with brown sleeving in to the Brown terminal.
    The reds all twisted together need to be in a terminal of there own safely insulated.
    Green into the earth terminal.

    Thanks Philip - this is how we had wired the light, but the switch will now not turn the light off.

    Thinking the switch may have an issue as it won't click down flush any longer. Could it just be a case of replacing the light switch?

    Unfortunately the person wiring did not take a picture of the previous arrangement - it also went into a 4 port box, rather than a 2 port. A rookie error for sure!

    Thanks for all your help.

    You may have fried the switch with your random wiring attempts. before you buy a new one, try this:
    Power off
    Remove one wire from the switch itself, insulate the end of the wire
    Turn the power back on,
    if the light is now off then you need a new switch. If it’s still on, you have a wiring error.
