[What is the most diamonds everyone here has found]

It's not important but 54 diamonds...

[What is happening to my server?]

When I turn on my server and join it, it instantly kicks me and goes offline. Does anyone know why this is happening? I can't run commands either, so therefore I know the server TPS is 0, but why?

[How do I fix this? ONLY 1 error, please help!]
