List all the plugins on the server. If you have multiverse remove it to test if its the issue If Multiverse isnt the issue backup your players folder. Once backed up remove it and restart server. See if you can log in. If you can log in without a issue your player file became corrupted Also try viewing this post it may help. http://forums.bukkit.org/threads/cant-get-rid-of-bugged-player-entity.69798/#post-1075548
I know what the issue is. Its the plugin "NoLagg", you can test it by doing /nolagg reload, then type in any command EG: /spawn and you will be kicked from the server for "Internal Error". Fixes: - Delete your nolagg and bk common (files+jars) Then reinstall the latest versions of both of those plugins. If your running myworlds do the same
