Hello all. I decided i would change all of the light switches and power sockets in my house as the previous owners ended painting all over them and they looked a mess. Changed the the second floor light switches and everything is good. Started on the 1st floor and stopped half way to run some errand. Came back and finished but now the lights do not work at all on the 1st floor and one room on the 2nd floor. The ground floor lights are fine. Is it likely I’ve wired something wrong? I’m fairly certain I put the wires in the their equivalent hole on the new switch.
