side by side light swithes not working
As beenthere said, get those regular outlets out, and put in the GFCI’s. Replace the bad one with another one. These aren’t there to annoy people, they’re there for the protection of people.
The problem with the power at the switches could have been caused when the outlets were changed…a loose wire, a wire hooked up wrong, etc. It sounds like of the 3 cables entering the switch box, one will be the incoming power, with it’s black wire connected to each switch (probably via the white jumper wire you mentioned, and if so, should have been a color other than white or green). The black of the other 2 cables would go to the lights they control, and also hooked to the switches. The white wires, in this case, would be connected together, just like you mentioned.
Just because you can, doesn't always mean you should
