How to remove a local player on minecraft ps3?

So I got ps3 minecraft and I played split screen for a little. When my sister and I were done playing Minecraft I wanted to play online with my friends but the account my sister was on had network disabled. So then I try to join my game with online but it says I can't because of the local player. I know that I can just turn on the network on her account but I also want to know how to get the local player off anyways.

Try going out of the game then go back in or try turning off the ps3 than back on to remove the local player. Turning it off worked for me.
