Hey guys I’m new here and really scratching my head on this.
Bought a new light and had to change the ceiling rose to accommodate. Took a pic of the old rose, made sure to follow the connections in the picture in the new terminal block, and now the light stays on constantly! The pull cord switch has no effect. I tested the switch with an ohmmeter and it opens and closes as expected.

So what on earth could be wrong??

So confused so if anyone can help out that would be great

Doesn't look like you have used the switched live, hence your issue.

Also, those chewed out holes look very rough. Hopefully no damage was done to the cable when it was pulled through them.

As above that is a rough job those entries need protection. The brown from the light needs to go with the blue wire with the brown sleeve on it.

Genius. That’s why you guys are professionals and I’m not!
Thank you very much. It worked

Thanks mate. Your clear description really helped illustrate what DPG said to solve the problem
