  • Hello,


    The following error occurs on my server (see below).
    The message runs in the chat constantly and i have to restart the server to be able to use (write/read) the chat again,
    Is there a solution for this problem? Thx.

  • you may have a bad plugin. 1 that interferes with another. check your plugins. If you installed any lately try disabling them 1 at a time till you find the problem starting with the last you installed. you can add a .1 behind the .jar on the .jar files to disable them and restart the server to reset them. I know it is a bother but the only way I know how to troubleshoot the problem. You will probably have to shut the server down to disable the plugins then restart it.

  • Yes, this problem comes from my iConomy. I look at this problem. It comes anyway soon a new update for iConomy.


    EDIT:
    And already I have the cause: The plugin tried to close a GUI by timer. But this player has just gone offline. The plugin did not find the player.



    Will be fixed in the next update!

  • Hi,


    1. is normal. It comes from the Game.


    2. That is not an Error of iConomy. That is an Error of the Game. I got the same Error. But only @red51 can do something.


    Tip: Disable the debugging of ActiveSign. It looks like it's working normally.


    When the debug is on, it takes much longer for ActiveSign to process everything.
