[lvarayut]

The problem occurred because of the different version of KnpMenuBundle required. Change the "knplabs/knp-menu-bundle" From:

"require": {
//...
"knplabs/knp-menu-bundle": "dev-master"
//...
}

To:

"require": {
//...
"knplabs/knp-menu-bundle": "~1.1"
//...
}

[rande]

KnpMenuBundle 1.1 and 2.0 are now supported
