title: not able to insert term programatically
body: <p>I am trying to add terms using code but it's not added into wordpress. I am using below code to add </p>
  
  <pre><code>$term = wp_insert_term('Jogger', 'product_style',0);
  </code></pre>
  
  <p>Every time it return <code>Invalid taxonomy</code>. I have check my db and I don't found any entry for this. Even I have check with <code>term_exists('Jogger', 'pa_style',0);</code> and it also return 0. Can some have any idea about it.</p>
