btw. on my end the anchor even works on mobile:

Du musst mehr Augenmerk auf das Cookie Handling setzen. Selbst wenn ich alles ablehne bei deiner Seite sehe ich folgende Cookies munter senden:

Auf welcher Enfold Version läuft deine Installation – gefühlt glaube ich das gibt es schon ewig dort.

Edit: hattest du nicht von Listenelement gesprochen – über welches Element reden wir ? Rasterelement ( da muss ich erstmal schauen was das ist- ich nutze meist die englische Oberfläche)

Jetzt verstehst du auch meine Frage: wo das Listenelement auf deiner Seite ist. Du sprichst hier über ein anderes Element. Icon/Flipbox Grid

that filter set in child-theme functions.php removes the anchor and onty the image is inserted instead.

add_filter( 'avf_post_ingnore_featured_image_link', '__return_true' );

btw. that filter can be selective to posts from f.e. categories:

function custom_avf_post_ingnore_featured_image_link( $ignore_image_links ){
  //  e.g. available variables
  global $avia_config, $post_loop_count;

  $ignore_image_links = in_category( array( 1, 'grafik' ) ) ? true : false;
  return $ignore_image_links;
}
add_filter( 'avf_post_ingnore_featured_image_link', 'custom_avf_post_ingnore_featured_image_link', 10, 1 );

the other way round ? the first is your edited version – and the second the existing enfold one?

I run many portfolios – and I have never seen such a fatal error on my websites. As you mentioned, there are no other messages about this on the forum.
What exactly are you changing manually? – Do you have any custom post types running?

on : avia-snippet-widget.js i commented out the first regex – hope that this will not come into conflict with other settings.

function av_pretty_url(text)
{
	return text.toLowerCase()
		// .replace( /[^a-z0-9]+/g, "-" )
		.replace(/ /g,"_")
		.replace( /^-+|-+$/g, "-" )
		.replace( /^-+|-+$/g, '' )
		.replace(/ä/g, 'ae')
		.replace(/ö/g, 'oe')
		.replace(/ü/g, 'ue')
		.replace(/ß/g, 'ss');
}

see: https://webers-testseite.de/datenschutz2/
for example datenschutzerklärung

download it here (both files min.js too) : https:://webers-testseite.de/avia-snippet-widget.zip

you know how to have child-theme js files?

first: on fontello there is on top the option to give them a name.
second: before uploading – rename those zip files to something reflecting the icons ( as on enfold : enfold medical icons etc. )
( This is only to have in media-library a meaningfull name – not important for the function )
see: https://kriesi.at/documentation/enfold/icon#download-fontello-or-flaticon-icons-included-in-enfold-demos

PS : inside the zip-file there is a folder with fontello-123456xyz – you can leave that. important is to rename the zip file and the font on downloading on fontello.

it seems that you have all pages with transparency option ?
so you can overwrite the behaviour to show now the alternate logo anyway. on all mobile devices
This is merely an emergency solution now

.responsive.avia_mobile #top .header_bg {
  opacity: 0.1;
}

.responsive.avia_mobile #top #header:not(.av_header_transparency) .header_bg {
  opacity: 1;
  background-color: rgba(0,0,0,0.2) !important;
  -webkit-backdrop-filter: blur(5px);
  backdrop-filter: blur(5px);
}

.responsive.avia_mobile #top .av_alternate_logo_active .logo a > img, 
.responsive.avia_mobile #top .av_alternate_logo_active .logo a > svg {
  opacity: 0;
  width: 200px
}
.responsive.avia_mobile #top  .logo img.alternate, 
.responsive.avia_mobile #top  .logo .subtext.avia-svg-logo-sub {
  display: block;
  opacity: 1;
}
.responsive.avia_mobile #top  .logo img.alternate, 
.responsive.avia_mobile #top  .logo .subtext.avia-svg-logo-sub {
  display: block;
  padding: 10px 0;
}

.responsive.avia_mobile #top .logo img.alternate, 
.responsive.avia_mobile #top .logo .subtext.avia-svg-logo-sub svg {
  top: 50%;
  transform: translateY(-50%);
}

nevertheless – you had to find the reason for that url mismatch – and why the normal logo could not be overwritten by a new uploaded one.

you uploaded that svg file from the Flaticon zip to fontello.
Do you have any warning on uploading? (Compound path … )
Are these icons monocolor icons?
Do you see the icons on fontello as you like to have it?

like this: https://kriesi.at/themes/enfold-2017/#best-rated
but you know how to insert those icons – the only problem is to get them centered – allthough you have tried using the text-align feature of the editor?

have a look at this small plugin: https://gitlab.rrze.fau.de/rrze-webteam/rrze-post-expiration
(GNU General Public License v2.0 or later – so you can use it)

you will have then on all posts under publishing the post :

after expiration those post/pages goes to an extra “Expired” State.
PS – there is only the setting for post/pages not for portfolio. BUT only two places in sourcecode can change that to have it for portfolio too.
/includes/main.php (line 86 – add to the array ‘portfolio’ )
and
/includes/settings.php (line40 – add a new line with portfolio)

What have you inserted to your :
Dashboard – Settings – General : “WordPress Address (URL)”. and “Site Address (URL)”. ?

why does logo image url differ to domanin url?

https://october7coalition.org

on mobile the normal logo (non transparency case ) is shown and this leads to :
https://october7coalition.org/wp-content/uploads/2024/01/logo_black.png
on desktop the transparency logo is shown so the alternate logo inside sub-text is there.
https://october7coalition.com/wp-content/uploads/2024/01/logo_black-300x133.png

you can have on child-theme functions.php :

function add_slug_body_class( $classes ) {
global $post;
  if ( isset( $post ) ) {
    $classes[] = $post->post_type . '_' . $post->post_name;
  }
  return $classes;
}
add_filter( 'body_class', 'add_slug_body_class' );

then a post/portfolio/page will have on body (#top) an additional class f.e.
post_name-of-my-post
portfolio_name-of-my-post
page_name-of-my-post

maybe that helps you to better select.
On your example page it will then be : post_sand-box-post

why do i include to that class the post-type? because it might be that you have post and a page with same slug – then you can differ between them
if you do not need that – remove the instertion of the post-type:

function add_slug_body_class( $classes ) {
global $post;
  if ( isset( $post ) ) {
    $classes[] = $post->post_name;
  }
  return $classes;
}
add_filter( 'body_class', 'add_slug_body_class' );
