Multiplayer is disabled and will not turn on

Hello, 

I’ve been playing Minecraft for awhile now but the new update has becoming a little confusing. Before going into a world, 99% of the time it asks you to change your skin (due to not being able to use it in multiplayer), so that has been what I have been doing. When playing, I accidentally pressed on continue. The skin changing notification says it disables multiplayer on that world, but I just ignored that, thinking that I could change it back to multiplayer later. When trying to play Minecraft with my friend later in the day, I found that she could not join my world. So I went into the world edit and turned the multiplayer on and pressed play. My friend could still not join. I checked the multiplayer settings in the world, and they were off and grayed out. I though that I forgot to turn them on so I turned them on in world edit and went in again. When I looked at the world settings ingame, they were still off.

I guessed it was the skin notification, but I couldn’t find anything about it. If this could get fixed, that would be appreciated greatly, since the world I played on with my friend took a lot of hard work and it would be disappointing not to play on it anymore.

Thanks.
