Hi Rakesh, sorry I've just check the forum :p and thx for the report, I think the problem is on my sendMessage function on ui.js file. Please update the function with this one: [pre] /** * send message to another user */ function sendMessage(b, i, u, f, s, to, from, msg){ if (!Sarissa || !document.getElementById) return; var xmlhttp = new XMLHttpRequest(); xmlhttp.open('POST', 'send.php', true); xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send("action=sendMessage&b="+escape(b)+"&i="+escape(i)+"&u="+escape(u)+"&font="+escape(f)+"&s="+escape(s)+"&to="+escape(to)+"&from="+escape(from)+"&msg="+escape(msg)); } [/pre] and if you still face a problem, feel free to contact me via email: andre_flea@yahoo.com Thx, Andre
