title: WordPress Advanced Custom Fields - Meta Query no result
body: <p>I am using WPML and ACF in my WP.</p>
  
  <p>Now I wanna list posts from the category ID 399 with the ACF Field "organization_type" and the value key "socialbusiness" but they do not show up.</p>
  
  <p>This are my query tries:</p>
  
  <pre><code>        $args = array(
              'post_type'     =&gt; 'post',
              'cat'      =&gt; 399,
              'posts_per_page'    =&gt; -1,
              'meta_query'        =&gt; array(
                  //'relation' =&gt; 'OR',
                  array(
                      'key' =&gt; 'organization_type',
                      'value' =&gt; 'socialbusiness',
                      //'compare' =&gt; '='
                  )
              )
          );
          //unset($args);
  
          $args = array(
              'numberposts' =&gt; -1,
              'post_type' =&gt; 'post',
              'cat' =&gt; 399,
              'meta_key' =&gt; 'organization_type',
              'meta_value' =&gt; 'socialbusiness'
          );
  
          // query
          query_posts( $args );
          while( have_posts() ) {
  </code></pre>
  
  <p>What am I doing wrong?</p>
