can you try this in your child-theme functions.php:

`add_filter(‘gettext_with_context’, function($translated, $text, $context, $domain){
if($context = ‘playlist item title’ && $text == ‘“%s”’) $translated = “%s”;
return $translated;
}, 10, 4);`

that was transfered to bad signs – please copy&paste from here:
https://kriesi.at/support/topic/is-it-possible-to-disable-quotation-marks-in-the-track-name-of-a-playlist/#post-1232704

Fix for that

must be in av-helper-slideshow.php.

just one moment …

Edit: it is on line 724:

$html .= '</' . $tags[1]. ' ">"';

replace with:

$html .= '</'. $tags[1].'>';

so you have no comment-count nor author behind that?

.text-sep.text-sep-date {
    display: none !important;
}

on that add_action line can you please do this :

add_action('wp_footer', 'unmute_mute_background_video', 999);

so that there is:

function unmute_mute_background_video_in_slider(){  
?>
<script type="text/javascript">
(function($) { 
    $('.mute-button .avia_video').closest('.avia-slide-wrap').prepend('<div class="custom-mute"></div>');
    $('.mute-button .avia_video').on('av-mediajs-loaded', function() {   
      var video = $(this).mediaelementplayer();
      video[0].setMuted(true);
      $('.avia-slide-wrap').on('click', '.custom-mute', function() {
        if(video[0].muted === true) {
          video[0].setMuted(false);
          video[0].setVolume(0.5);
        } else {
          video[0].setMuted(true);
        }   
      });
    });
    
    $('.avia-slide-wrap').on('click', '.custom-mute', function() {
      $(this).toggleClass("icon-sound-on");
    });
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'unmute_mute_background_video_in_slider', 999);

now without function ready

i answered you per mail – i do not know why.
it seems that everything is done on your site. But the div.custom-mute isn’t inserted.
You can see on the test-page link i send you via e-mail that even with your video ( but downsized to 26MB) it works.
( it works on my side here even without document ready or window load function. )
And even if i got two videos on the slider – i do not need to have the custom-mute div generated on an each function. – it works the way above – all video slides will have that buttons.

Even the div.custom-mute isn’t inserted – so please try with document ready function:
( i can create the div via developer tools console – so the selectors are correct )

function unmute_mute_background_video(){
?>
<script type="text/javascript">
(function($) { 
$(document).ready(function(){  
    $('.mute-button .avia_video').closest('.avia-slide-wrap').prepend('<div class="custom-mute"></div>');
    $('.mute-button .avia_video').on('av-mediajs-loaded', function() {   
      var video = $(this).mediaelementplayer();
      video[0].setMuted(true);
      $('.avia-slide-wrap').on('click', '.custom-mute', function() {
        if(video[0].muted === true) {
          video[0].setMuted(false);
          video[0].setVolume(0.5);
        } else {
          video[0].setMuted(true);
        }   
      });
    });
    
    $('.avia-slide-wrap').on('click', '.custom-mute', function() {
      $(this).toggleClass("icon-sound-on");
    });
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'unmute_mute_background_video');

Among the faq’s is on default : how to exclude the current post from post slider when you show a post slider on a single post. But this is not the thing you like to know?

may i see that page please.

or rename it – f.e. diamond_sponsors, platinum_sponsors, gold_sponsors etc.

Go to your Dashboard – Enfold ( or Enfold Child if you working with it ) – Header : 2nd Tab “Header behavior”
uncheck “Shrinking Header”

On Header Layout you can set up a custom pixel value on header size.

The ID sponsors is not unique ! There are two sections same ID

What would a postman do if he found two mailboxes with the same name? : Nothing

you can have diamond_sponsors, platinum_sponsors, gold_sponsors etc.
and be aware of that IDs and their anchor-link is case-sensitive and spaces are not allowed

by the way – nice sideeffect is that you can group images in different color-sections with that method.

if you have images inside a text-block element – you can edit those images. Insert then into the link css class field – your group-x you like

by this case you had to add on the code above one line – because the class: group-x goes directly to the lightbox-added class – so there is no space between the classes – both are on the same anchor.
( on the image alb the group class is on the parent element )

        $('.lightbox-added').each(function(index, element){
          	$('.group-'+index+' .lightbox-added').attr('data-group', index);
		$('.group-'+index+'.lightbox-added').attr('data-group', index);
	});

see again on the bottom of the test-page: https://webers-testseite.de/lightbox-grouping/

but your video is not a self hosted one?

all those alb element do have names – it is easy to mention that? Fullwidth Sub Menu

And no – you didn’t explain it not well – you did explain it wrong : because

My menu is a mega menu and to make it multiple columns, I checked “This column should start a new row” checkbox on one of my menu items

As described above not that mark in “start a new row” checkbox indicates a new column. A column is a column – and a row a row.

But sorry to say that – then you have to wait for the mods to look in here – because as a participant I can’t see the private content.
