When I join to my server, it stops to work and says a crash error. Only it do some times, no everytime. This is the crash error. Sorry for my english: http://pastebin.com/DZfMywsp There isn't any MineCraft Crash report and there isn't no more than the messages of ClearLagg.
[15:59:59] [Spigot Watchdog Thread/ERROR]: fr.xephi.authme.cache.backup.FileCache.createCache(FileCache.java:110) There appears to be an issue with AuthMe creating a Cache. Try updating. There is also a plugin (of which name has escaped me) which was AuthMe updated to 1.8 I believe.
Ah my mistake, i read the comments above and read the crash log wrong, they are correct it is "AuthMe", I suggest deleting it
I have bad experience with AuthMe, it didnt load the config and i had the exacly same version what AuthMe supported.
