Get Internal server error when I connect

[waawaaaa]

When I try to connect I get the message "Internal server error" due to a hacker hitting me with a splash potion which apparently has also given me keep inventory which makes /suicide not work when using pickaxe chat, this has also affected other players. Is it possible to have these effects removed?
