title: WooCommerce product attributes gone
body: <p>I've been working on my WordPress/WooCommerce site all morning.  An now, all of a sudden, my Product Attributes have no values. </p>
  
  <p>If I add a new product attribute value (via the product attribute page), the new value also does not show.  </p>
  
  <p>If I look in the database, all the values are there and the data looks perfectly fine, references and all.</p>
  
  <p>I've done nothing to the taxonomy terms (except read them in a little theme code I'm writing).</p>
  
  <p>I've even looked at my GIT and nothing has changed that has any impact on product attributes.</p>
  
  <p>I am completely stumped as nothing is making sense.  I'm starting to wonder if it's bad mojo, as another site of mine has also decided to magically stop working without reason.</p>
  
  <p>Any ideas anyone?  I'm a tick away from going nutts.</p>
