But please read carefully.

Recommendations

Add rel=”noopener” or rel=”noreferrer” to each of the links that Lighthouse has identified in your report. In general, when you use target=”_blank”, always add rel=”noopener” or rel=”noreferrer”.

Or : means – nofollow will be enough to add.

btw: you can reach this via child-theme functions.php
adjust the webers-testseite.de through your home domain url:

add_action('wp_footer', 'open_external_links_in_newtab');
function open_external_links_in_newtab(){
?>
<script type="text/javascript">
(function($) {
	$('a').not('a[href*="webers-testseite.de"]').attr({
		'target':'_blank',
		'rel': 'nofollow',
	})
})(jQuery);
</script>
<?php
}

means that any link that does not match your domain url will be considered external and will be opened in a new tab with the attribute nofollow.

it is allways better to have the livelink to say something
but isn’t it the normal behavior to have the image title under the lightbox image?

may i ask before some questions: Did the child-theme has a different – more personalised name?
Where did the infogov_theme come from?

Did you rename your dynamic stylesheet via that known snippet?

add_filter('avia_dyn_stylesheet_file_path', 'avia_change_filename');
function avia_change_filename($stylesheet){
return 'myfilename.css';
}

Wobei da im Regelfall keine Einträge sein sollten/müssen.

you can try this in your child-theme functions.php to place for logo and alternate logo title and alt attributes:

function custom_logo_attriubtes(){
?>
<script>
(function($){
	$('.logo img').attr({ title:"Tobias Glawe Fotografie", alt:"Fotograf Hannover - Tobias Glawe Fotografie" });
	$('.logo img.alternate').attr({ title:"Tobias Glawe Fotografie", alt:"Fotograf Hannover - Tobias Glawe Fotografie" });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_logo_attriubtes');

First time i recognized this.
But this must be done : i have in my quick css a background set to f.e.:
url(/wp-content/uploads/Seal.png ) and it will end up in: url(/wp-content/uploads/dynamic_avia/Seal.png )
that the merged css is in that folder is ok – but the links to the images are still not in that folder !!!
That is a bug.
I noticed it here first time : https://webers-testseite.de/multiple-background-images/ where there are multiple background-image definitions. When i turn on the merging – the images are not found.
Do i have to address now with absolute path?

Wie hast du das gemacht. Nur die Einträge in den Einstellungen – Allgemein geändert, oder wirklich in der Datenbank.
Weshalb ich frage: Das mit der Datenbank wäre der richtige Weg. Wenn man das machen möchte ohne große mysql Kenntnisse zu haben geht es mit einem kleinen Plugin : Search und Replace
Da kann man die Datenbank zunächst sichern und dann umstellen. Da du aber schon die Url umgestellt hast, ist ein suchen und ersetzen wohl besser dann.
man kann alle Tabellen markieren und dann zB.
http://www.xmpublishing suchen und ersetzen durch:
https://www.xmpublishing

man kann auch erstmal einen Testlauf machen und dann in die Datenbank schreiben.
bei der kompletten Url wird er meckern, da dies für den “Replace Domain Url” vorgesehen ist.
nur https gegen http ersetzen wäre fatal.

F.e. if you like to replace all h2 headings in the slider with h1 – put this into your child-theme functions.php

function replace_tags_with_tags(){
?>
<script>
  (function($) {       
      function replaceElementTag(targetSelector, newTagString) {
        $(targetSelector).each(function(){
          var newElem = $(newTagString, {html: $(this).html()});
          $.each(this.attributes, function() {
            newElem.attr(this.name, this.value);
          });
          $(this).replaceWith(newElem);
        });
      }
      replaceElementTag('.avia-slideshow h2', '<h1></h1>'); 
  }(jQuery)); 
</script>
<?php
}
add_action('wp_footer', 'replace_tags_with_tags');

if you just want this only on that page set an if-clause:

function replace_tags_with_tags(){
if(is_page(504)){
?>
<script>
  (function($) {       
      function replaceElementTag(targetSelector, newTagString) {
        $(targetSelector).each(function(){
          var newElem = $(newTagString, {html: $(this).html()});
          $.each(this.attributes, function() {
            newElem.attr(this.name, this.value);
          });
          $(this).replaceWith(newElem);
        });
      }
      replaceElementTag('.avia-slideshow h2', '<h1></h1>');
  }(jQuery)); 
</script>
<?php
}
}
add_action('wp_footer', 'replace_tags_with_tags');

To explain the behaviour more precisely. If you have only selected Title Display in the settings of the Masonry, this should also apply to the elements that appear after pressing the “Load More” button. However, this is not the case; the title and description are then displayed for those elements.

Enfold in the newer versions ( definitly on 4.5.4 ) got on Theme Options at the bottom: “Select Your Editor” There you have the choice.
By the way: My Recomendation is for the devolopers to set the standard not to ‘ ‘ but to : enable_wp_classic_editor

:lol :roflmao

yes – flexbox model is a very powerful tool, which is rarely used properly.
But only for that case Header Left or Right. And as he had only one container_wrap class

by the way – you don’t need to hold the tree structure after /shortcodes
so you can put in all edited ALB to the shortcodes folder itself – no need for subfolders.

I think I’ve never written such an elegant solution to have the footer below – but it seems there was no interest in a good solution. – What a pity

Video unbedingt runterrechnen: 45MB ist einfach zu viel für ein Self Hosted Video.
Zumal das SD Video auf Vimeo zB 19MB hat.

oder mal Cloudinary anschauen, ist sehr gut und für normalen Traffic kostenlos.
Das wird in Enfold wie selfhosted gewertet. Also kann auch so gehandhabt werden.

bitte mal das Merging abstellen bei Enfold Options.
Da kann ich die Seite besser durchsuchen.
