Preview big : I find this code – but do not know where I can disable this.

Hey lauterkeit,
I believe that your featured image is not showing due to a script in your child theme functions.php, try looking there, or include admin login in the Private Content area so we can be of more assistance.

Hi,
Thanks for the login, the cause was this custom script:

function metaAfterTitle(){
?>
 <script>
 jQuery(".template-blog .post-entry").each(function(i) {
        var postTitle = jQuery(this).find('.blog-categories.minor-meta');
        var metaInfo =  jQuery(this).find('.post-meta-infos');
        jQuery(metaInfo).insertAfter(postTitle);
       });
 </script>
<?php
}
add_action('wp_footer', 'metaAfterTitle');

I changed it to this:

function metaAfterTitle(){
?>
 <script>
 (function($){
 $(".single-post .post-entry").each(function() {
        var postTitle = $(this).find('.post-title.entry-title ').css({'margin-bottom':'0','padding-bottom':'0'});
        var metaInfo =  $(this).find('.post-meta-infos');
        $(metaInfo).insertAfter(postTitle);
       });
})(jQuery);
 </script>
<?php
}
add_action('wp_footer', 'metaAfterTitle');

Please clear your browser cache and check.

Hi,
I didn’t check the Aktuell page, I was looking at the post that you had originally linked to.
So to work for both I change to this:

function metaAfterTitle(){
?>
 <script>
 (function($){
$("article.post-entry").each(function() {
        var postTitle = $(this).find('.post-title.entry-title ').css({'margin-bottom':'0','padding-bottom':'0'});
        var metaInfo =  $(this).find('.post-meta-infos');
	 $(this).find(metaInfo).insertAfter( $(this).find(postTitle));
       });
})(jQuery);
 </script>
<?php
}
add_action('wp_footer', 'metaAfterTitle');

and adding this css for a category was too close the date on the Aktuell page.

.html_modern-blog #top.page-id-16257 .post-entry .blog-categories {
    top: -15px;
}

This script doesn’t affect the sidebar on your Aktuell page, it was down because you have a color section on the page, I disabled the sidebar and added it using the widget element and now it shows correctly, please check.

Best regards,
Mike

Hi,
On the start page was a different element showing the blogs, I adjusted your script so now it works of all three of these situations, do you have any more places that you need to move the date?

function metaAfterTitle(){
?>
 <script>
 (function($){
$("article.post-entry").each(function() {
        var postTitle = $(this).find('.post-title.entry-title ').css({'margin-bottom':'0','padding-bottom':'0'});
        var metaInfo =  $(this).find('.post-meta-infos');
	 $(this).find(metaInfo).insertAfter( $(this).find(postTitle));
       });
$("article.slide-entry").each(function() {
        var slideTitle = $(this).find('.slide-entry-title.entry-title').css({'margin-bottom':'0','padding-bottom':'0'});
        var slideMeta =  $(this).find('.slide-meta').css({'margin-top':'0','padding-top':'0'});
	 $(this).find(slideMeta).insertAfter( $(this).find(slideTitle));
});
})(jQuery);
 </script>
<?php
}
add_action('wp_footer', 'metaAfterTitle');

As for your sidebar, you are correct this should work, I copied your page /medien/ to my test site and the sidebar show as on your live site, but on your staging site the page structure is not correct, the sidebar is outside the #main div, so there is a conflict somewhere that is not on your live site.
How did you copy your site to the staging site?
Typically this kind of error is due to unclosed tags or html in title fields which can be hard to find, when did you notice this error? Do you remember what you were working on?
Try disabling all of your plugins. If that resolves the issue, reactivate each one individually until you find the cause.
If this doesn’t help try creating a second staging site of the original to ensure that this process is not what caused the error.
