das war ja auch gedacht um den Title vom Breadcrumb in etwas anderes zu transformieren als ein h1.
Dann würde das ja die Doppelt h1 Problematik lösen.
Wie gesagt – besser wäre es das Plugin , welches für den Shortcode zuständig ist zu betrachten.
der wird wohl das h1 setzen.
Denn das: <h1 class=”the_input_element” data-math-equation=”” data-original-math-equation=”” data-decimal-places=”0″>Angebot für eine PV-Anlage</h1>
ist nicht von Enfold seite aus gesetzt worden.

Kann ich deine Seite mal sehen?

ich vermute mal, das ihr das händisch erledigt habt. ( via ftp und dann Datenbank bearbeitet )

Ich nutze Duplicator Pro ( die kostenlose Freie Version ist aber entsprechend gut – es fehlen nur die Scheduling Möglichkeiten )
hier wird alles zu der neuen Domain korrekt migriert.

Duplicator macht zwei Dateien bei der Sicherung. Eine installer.php und einen Archiv File ( zip – oder dup – je nach einstellungen)
Sinnvoll setzt Duplicator sogar Plugins wie (WPS Hide Login ) auf deactiviert – und gemahnt danach es wieder zu aktivieren.

I assume that you have done this manually. ( via ftp and then edited the database )

I use Duplicator Pro ( but the free version is good enough ; only the scheduling options are missing )
everything is migrated correctly to the new domain.

Duplicator creates two files during the backup. An installer.php and an archive file ( zip – or dup – depending on the settings )
Duplicator even sensibly sets plugins such as (WPS Hide Login) to deactivated – and then reminds you to reactivate them.

… sorry – soon there will be something more informing …

edit. a quick way is to replace that enfold h1 tag with jQuery in your child-theme functions.php:
or – maybe better try to change the heading in your shortcode of the plugin.

function breadcrumb_change_tag(){
?>
<script type = "text/javascript">
window.addEventListener("DOMContentLoaded", function () { 
	(function($) {
	  $("#top #main .title_container .main-title").contents().unwrap().wrapAll('<div />');
	})(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'breadcrumb_change_tag');

but i guess we can influence the heading via filter : avf_title_args – …
if there is a possiblility to influence the building of an element – it is alway better than to change it afterwards – so use the next solution instead.

yes thats it – ( and btw. the way you described that “problem” was a bit misleading.

If I understand you correctly, then you have, for example, a page that is 1000px high – and you want to shrink the header over this entire scroll distance, e.g. from 100px to your 54px.
But that would mean that the header should only shrink by fractions of a pixel per pixel of scroll distance? I don’t think this is possible.
However, if you only want to have a delayed shrinkage, i.e. I first scroll 100px without anything happening to the header, and only then should the shrinkage start, that could be possible.

The thing is, you didn’t mention that you were using the hamburger from the start.
I can see the item but it is set to display none by css code.

to see a first result bring this to quick css and look:
( a little bit more css to see selectors if influnce )

#top .menu-item-cart.menu-item-avia-special  {
  display: block !important;
}
#top .menu-item-cart.menu-item-avia-special a {
  font-size: 24px !important;
}
.av-burger-overlay-active #top .menu-item-cart.menu-item-avia-special a {
	color: #FFFFFF !important;
}
#top .menu-item-cart.menu-item-avia-special a:hover {
	color: #9d1a18 !important;
}

and don’t forget to replace the “#” by the link of that cart icon

get rid of the class: menu-item in that snippet:

function add_cart_icon_to_main_menu( $items, $args ){
  if ($args->theme_location == 'avia'){
    $cartLink = '<li class="menu-item-cart menu-item-avia-special" role="menuitem"><a aria-label="Cart" href="#" rel="nofollow" aria-hidden="false" data-av_icon="" data-av_iconfont="entypo-fontello" alt="Cart" ><span class="avia_hidden_link_text avia-menu-text">Cart</span></a></li>';
    $items =  $items . $cartLink;
  }
  return $items;
}
add_filter( 'wp_nav_menu_items', 'add_cart_icon_to_main_menu', 9999, 2 );

In fact, you could do it with a hook as well. – but i would use a wordpress hook on that.
The main navigation menu theme_location is avia.
( you see that you can use that hook also to other menu locations :
avia(main-menu), avia2( top-menu), avia3(footer-menu) )

function add_cart_icon_to_main_menu( $items, $args ){
  if ($args->theme_location == 'avia'){
    $cartLink = '<li class="menu-item menu-item-cart menu-item-avia-special" role="menuitem"><a aria-label="Cart" href="#" rel="nofollow" aria-hidden="false" data-av_icon="" data-av_iconfont="entypo-fontello" alt="Cart" ><span class="avia_hidden_link_text avia-menu-text">Cart</span></a></li>';
    $items =  $items . $cartLink;
  }
  return $items;
}
add_filter( 'wp_nav_menu_items', 'add_cart_icon_to_main_menu', 9999, 2 );

replace that “#” in the snippet with your prefered link

this will insert a new menu-item to the main nav. But: it will be the very last menu-item even behind the search icon and even behind the hamburger icon itself.
Same here moving it to the right position is easy with that extra class from snippet ( menu-item-cart)

function move_cart_icon_before_burger() { 
?>
<script>
(function($){
  $('li.menu-item-cart').insertBefore($('li.av-burger-menu-main'));
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'move_cart_icon_before_burger');

to see that solution used : https://webers-testseite.de/

yes – and please – the update on 5.6.8. does not have that fixed.

test if the other selectors had to be set too!

.avia-image-container.av-hover-grow.av-hide-overflow, 
.avia-image-container.av-hover-grow.av-hide-overflow .avia-image-container-inner, 
.avia-image-container.av-hover-grow.av-hide-overflow .avia-image-overlay-wrap a.avia_image {
  overflow: hidden;
}

Did you try to embed the layerslider with its shortcode (on Project List hover the preview – click on the 3 dots on the top right – embed) ?

But you use justification there, don’t you?
With justified text, that’s exactly what often happens, that there are unsightly word spacing. You will have the same problem in Word. In Word, a more or less intelligent word separation is set.

so you have to decide now what to do if you set a text-block to justify.
By the way – how did you set this? because Tiny Editor does not offer – justified test.

you can use hyphens or word-spacing f.e.:

p {
    text-align: justify;
    -webkit-hyphens: auto;
    hyphens: auto;
}

some css properties ( text-justify; word-spacing ) are not well supported by all browsers. see: https://css-tricks.com/almanac/properties/t/text-justify/

f.e.:

p {
  text-align: justify !important;
  -webkit-hyphens: auto;
  hyphens: auto !important;
  text-justify: distribute;
  word-spacing: -0.05em !important;
  text-align-last: left;
}

but i would not use everywhere a justification. So it is much better if you set a custom class to those texts that should be justified.
and use the custom class to specified text.

btw – with the extra long words, which are separated unsightly, also a manually set “should break points” could be useful.
You can use for that the html entity: ­
this is short for softhyphenation – in Word this is called conditional line break
and there is a nonbreakinghyphen entity too Link. for words like “on-page”, “off-page”

as far as I understood it, only the one link should open in a new tab. The others should open on the same page.

so maybe use instead:

function open_custodiapestcontrol_links(){
?>
<script type="text/javascript">
window.addEventListener("DOMContentLoaded", function () { 
    (function($) {     
        $('.av-masonry-entry[href*="custodiapestcontrol"]').attr('target', '_blank');
    })(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'open_custodiapestcontrol_links');

or – if you like to open all external links ( links that have a different domain ) in a new tab ( with some exceptions like mailto etc. )
use:

function open_external_links_in_newtab(){
?>
<script type="text/javascript">
window.addEventListener("DOMContentLoaded", function () { 
    (function($) {
      var url = window.location.origin;
      $('a').not('a[href*="'+url+'"], a[href*="mailto:"], a[href^="#"], a[href*="tel:"], a[href*="javascript:;"] ').attr({
        'target':'_blank',
        'rel': 'noopener',
      })
    })(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'open_external_links_in_newtab');

(remove rel attribute if you do not like to set)

Das sollte man noch ein wenig verfeinern, und auch browser übergreifend – zumindest mit -webkit prefix machen.
Das animation timing – eventuell mit bezier Kurve animieren.

to this topic possibly one more. I have made the experience that plugins like : Post Types Order could interfere here.

it would be nice to participate as a participant ;)

i think ismaels code should work.
on looking for this from docu:

click on your CPT on dashboard and look to the url window on top – what post-type you see there

f.e. on portfolio ( which is a CPT too ). you see: edit.php?post_type=portfolio

try a shortform – then with the info you get from that url window

add_filter("avia_post_slide_query", function($query) {
    unset($query["post_type"]["vacature"]);
    return $query;
}, 10, 1);
