    Press any key to continue . . .
    and my server has just stopped loading and I have no idea why. If anyone could help me out that would be great.

    try deleting the usercache file in your servers root folder, it seems to be corrupted.

    well, that's what happens if you stay on old, unsupported and generally broken versions *shrugs*
     
  5. Except I'm on 1.8.8 and all my plugins are fully supported... My 1.8.8 version isn't a beta or dev version either, it was stable.

    its 1.8.8, its old. if there are bugs, they don't get fixed anymore.
     
  7. well yeah except it's never happened before lol, and I've been using it for like 1 year
     
  8. Try cleaning your root folder, only dtart with a bat file and thr server jar.

    its a bug in the vanilla sever. god knows what lead to this error, now you know what you need to do if this occurs again. the usercache is just a cache for uuids, no important infos.
     
  11. okay, thank you very much.
