Nice tip, place following code to your item-post.php, should work:
<script type="text/javascript">
// Set forms to active language
$(document).ready(function(){
var post_timer = setInterval(zara_check_lang, 250);
function zara_check_lang() {
if($('.tabbertab').length > 1 && $('.tabbertab.tabbertabhide').length) {
var l_active = $('.tabbertab.tabbertabhide').find('h2').text();
l_active = l_active.trim();
$('.tabbernav > li > a:contains("' + l_active + '")').click();
clearInterval(post_timer);
return;
}
}
});
</script>
