Title kind of explains it all; somehow how a while back my clan chat got disabled so i found a few good tutorials on How to add Server and then Client sided stuff;

Did those, Eclipse didn't know any problems but then when i go to Type into clan chat like

" / Hi "

It shows up in the console as Player blah blah command / hi

Then the client freezes;

Server Error;


Client;


I don't know what i did :L.
Anyone have ideas?
