You need to add
'post_type' => array('post', 'opinion')
to your $normal_args
array and maybe remove the meta_query
?. Are you sure you have any opinions
with a _custom_blog_enhome
of 1
?
Start from
$normal_args = array(
'post_type' => 'opinions',
'post_status' => 'publish'
);
and add arguments one by one and watch the results.
