Your former customisation in posts doesn't work anymore

Hi,
I asked you a few years ago for a customisation in my posts that showed the data on top of a post and not below.
That was the code you gave me for custom css:

/* Date beside categories*/
.responsive #top .post-entry .post-meta-infos, .responsive #top .post-entry .blog-categories {
    width: auto;
    clear: none;
    top: -25px !important;
    margin-top: 0px !important;
    padding-top: 0px !important;
}

.html_modern-blog .post-entry .post-meta-infos .text-sep, .html_modern-blog .post-entry .slide-meta .slide-meta-del {
display: none;
}

And I think this for the the functions.php:

function move_postmeta(){
?>
	<script>
		jQuery(window).load(function(){
			jQuery('.post-template-default.single.single-post  .post-meta-infos').insertAfter(jQuery('.blog-categories.minor-meta'));
		});
	</script>
<?php
}
add_action('wp_footer', 'move_postmeta');

But now the date is again shown under the blog post and not on top. Did you change any code within an update that disables the customisation?

Best regards,
Patric
