Php script dies on $couchebase->set, please help

Hi, I’m new to this.

here my issue…

<?php error_reporting(E_ALL); $cb = new Couchbase("", "", "", "default"); ?>

object(Couchbase)#1 (1) { ["_handle":“Couchbase”:private]=> resource(2) of type (Persistent Couchbase) }

Now if I do

<?php error_reporting(E_ALL); $cb = new Couchbase("", "", "", "default"); $cb->set("a", 101); ?>

This web page is not available…

What do i do wrong ? Installed latest version…
WAMP, php 5.5.7x64, apache 2.4.7 x64

Can you run this script with php-cli? What version of libcouchbase are you using and what version of php extension?

version 1.1.4dp1
libcouchbase version 2.2.0
