I once was the owner of a Realms Minecraft server that was hosted for several months back in 2014 (1.7). And recently, me and a few friends have decided to open that world back up with their free trials.

Unfortunately, one of my friends, who played on the original server back in 2014, has been having some troubles. Ever since the original Realms server we owned was shut down back in 2014, the world that was used on that Realms server has been giving one of us an error. The "Internal Server Error." We are not sure what causes it or how to fix it. I am going to note a few things that we've noticed about this error message.

1. The error is only showing up for this one player, and not the rest of us. This one player being "THEmotmotman". Everyone else can connect perfectly fine.
2. This player can connect to the server if we are playing the version the world was created on. (1.7) But none of the other versions past it.
3. We are not given an error code after the "Internal Server Error" message screen.
4. Any other world, like mini games for example, work just fine. It's just this one world that is broken.
6. The message pops up, even if we use "Open to lan" to host this world.
7. And back when this world was originally hosted in 2014, the player could connect very easily.
