    I have a small issue. I am not sure if its possible for someone else to fix this because it was programmed by my programmer however, I believe the source code is there so this can be modified. A skilled programmer should be able to solve the problem. I currently have users connected to a linux server and its showing errors. It is not able to connect even though the server is stable. When everything is working, it should show "connected" but right now its showing "disconnected" or "Reconnecting". I need this fixed as soon as possible. This will take a skilled programmer and server expert. My programmer is away so he cannot do it right now which is why I am requesting someone else.
