Sorry for my new question: you did that code to funcitions.php of parent theme?
Than it is probably important where you inserted it – that is why i wrote:

put this into your functions.php of your child-theme

can you look what php Version is running on those servers?

3) you can set the top bar via functions.php of child theme:

add_filter('avf_header_setting_filter', 'avf_header_setting_filter_mod', 9999, 1);
function avf_header_setting_filter_mod($header) {
	if(is_page(1625)){
		  $header['header_topbar'] = '';
	}
	return $header;
}

a display none is not displayed but allthough it is in the source-code

the logo itself is no background-image. For shrinking version you need a real image there :

you can change the logo by adding this to functions.php of your child-theme
if you want to have a different logo on mobile advices (even for ipad air etc)

function avia_custom_mobile_logo(){
if(wp_is_mobile()){
?>
 <script>
	jQuery(".logo img").attr("src", "http://path-to-mobile-logo/logo.png");
 </script>
<?php
}
}
add_action('wp_footer', 'avia_custom_mobile_logo');

if you like to have a different logo for small screen width. – that is something different. – and on performance reasons it is always problematic to measure screen-width permanently. – so on this case a debouncing could be a good advice

function av_dif_mobile_logo(){
?>
<script>
	jQuery(window).load(function(){
	if (jQuery(window).width() < 480) {
		jQuery(".logo img").attr("src", "http://path-to-logo/logo.png");}
	});
</script>
<?php
}
add_action('wp_footer', 'av_dif_mobile_logo');

Can not confirm to that
Please do open https://webers-testseite.de/cynthia/logo-move/
and even if you do not accept and open another page the message pops up.

so we now had to use these phrases for the signs in input-fields like headings or caption-titles

'###lt###'		=> '<',
'###gt###'		=> '>',
'###amp###'		=> '&',
'###91###'		=> '[',
'###93###'		=> ']',
'###quot###'	         => '"',
'###34###'		=> "'"

by the way i shortend the code –
It is also very unlikely to hit such a string. In principle, you replace the & and the semicolon with the rhombus #

'#lt#'		=> '<',
'#gt#'		=> '>',
'#amp#'		=> '&',
'#91#'		=> '[',
'#93#'		=> ']',
'#quot#'	=> '"',
'#34#'		=> "'"

PS : thanks – i know that Guenter could help in this case !
See here the icon-list in action : https://webers-testseite.de/cynthia/logo-move/

put this into your functions.php of your child-theme:

if(!function_exists('avia_debugging_info')){
  function avia_debugging_info() {
    // 
  }
}

on using the entities it works the first time – but if you open the iconlist again all less than signs are gone and the iconlist in frontend does not work anymore. So no chance for a second edit or to add list points here.

see here a solution: https://kriesi.at/support/topic/checkbox-contact-formular-to-data-security-contract/#post-940989

you can input that in the Form Element Label:

Das Teil muß verpflichtend sein und nicht preselektiert sein.

i tested it ( ampersand method ) – but it does not work as expected.

Maybe the other Günter can have a look at that. We need a coder here

ok – i ignored your reference – on iconlist headings it is a great desaster !

no solution for that ? !

Seit der Umstellung von kriesi.at auf https liegen die Bilder auch ganz woanders.
Kannst du herausfinden in welcher color-section das liegt? Du siehst ja in der Demo welche color-section das sein soll : https://kriesi.at/themes/enfold-construction/ Einmal in dem Gelben und dann unten in dem Grauen Bereich

Gehe also in die color-section die es betrifft und lade dort ein eigenes Hintergrund bild – das überschreibt das fehlende.
oder das Bild jetzt findest du in Vollauflösung unter: https://kriesi.at/themes/enfold-construction/files/2015/10/house-wire-model-fade-white.png

sicher aber du kannst ja das in ein media-querie setzen: ( musst selbst wissen wo dein hamburger menu startet)

@media only screen and (min-width: 990px) {
.html_header_top.html_header_sticky #top #wrap_all #main {
    padding-top: 148px !important;
}
}

ja weil der schatten “falsch” angelegt ist
bei Schattenwurf in eine Richtung wird der 4 Wert meist mit negativen Vorzeichen verwendet:
deshalb siehe meinen Vorschlag oben der wirft nur in Y-Richtung nach unten einen Schatten – eventuell ist !important wichtig:
Lass also die Einstellung ruhig drin und nimm stattdessen das ins Quick css

.av_minimal_header_shadow {
    box-shadow: 0 5px 12px -8px rgba(0, 0, 0, 0.8) !important;
}
