library doesn't load properly
<p>i created a flipbook with help of turn.js.</p>

<p>on my local machine everything works fine, but i load it on my test environment. the turn.js constructor function doesn't work. i have there the following code:</p>

<pre><code>$('#flipbook').turn();
</code></pre>

<p>in my test environment i get the error: </p>

<pre><code>Uncaught TypeError: Object [object Object] has no method 'turn'
</code></pre>

<p>do you have an idea what could be the problem, the file turn.js is loaded (i proved it in the loaded resources).</p>

<p>thanks in advance :)</p>
