PBW Status

[Ragnarok]

Whoops sorry, I was going to give more detail but got distracted.
The game is Return to Hell. And it will not boot them at all. I go to kick player and it asks if I'm sure I want to, I press yes and then the bottom frame goes to a 500 error. Here is what the error says:

Error: 500

Internal Servlet Error:

It does it everytime I try to boot them. I've tried a few different times now.
