HERE IS LIST OF MY PLUGINS:

damn I totally thought I would get some help.

 

take out no cheat plus, auto saver(use simple autosave) and paste ur startup script, and what os are u using? is it win server? put ubuntu, reinstall plugins and reinstall worlds.

 

Seriously? The answer is change your operating system?

 

This is more of a world related error, try restart server, if still fails, go world folder and try move out the session.lock file and start server up.

 

it was an error in the session lock, thank you so much!
