there are a lot of shortcodes which are now in a subfolder (iconbox, iconlist, hr etc) i believe on non ftp update these will not be erased – maybe that causes the wsod.
By the way the newest wordpress has an code debugger – which reduces the wsod on functions.php mismatches.
On former time an invalid code or double function names will cause a wsod too. Now you got a warning.

some hosters do not accept different adresses than the one set in general options of the wordpress install.
With CF7 – i now there is a different handling – and that works almost without any additional code .
i tried your code :

add_filter('avf_form_from', 'avf_form_from_mod', 10, 3);
function avf_form_from_mod($from, $new_post, $form_params) {
    $from = " (Email address hidden if logged out) ";
    return $from;
}

but than the short message isn’t displayed after sending

edit : and it is not sending – even when i use the code here: Link

you don’t need it for every page – but i guess that was the aim – and your test page has the same.

can you make a screenshot of your layout ?

The flex-grid has the advantage. that you can put in every alb you like to have – even columns ! and on responsive case the empty grids are automatically gone to display none.
If you can live with image shuffel – go and get for example : https://de.wordpress.org/plugins/responsive-full-width-background-slider/
this is an older plugin – but it works as you can see it on testpage. If you don’t set it up as autoplay but with shuffel – there will be each time you open a page a different background.

on your code above it looks like you want to redefine the magazine size.
redefine existing size

function custom_modified_thumb_sizes( $size ){
	$size['square'] = array('width'=>300, 'height'=>300 );			
	return $size;
}
add_filter('avf_modify_thumb_size', 'custom_modified_thumb_sizes', 10, 1 );

if you like to have f.e. masonry and magazine sizes to be selectable on image alb :

add_filter( 'image_size_names_choose', 'avia_add_selectable_images' );
function avia_add_selectable_images($sizes) {
	$newsize = array (
		'masonry' => __('Masonry Thumbnail','avia_framework'),
		'magazine' => __('Magazine Thumbnail','avia_framework')
	);
	if(isset($newsize)){
		$sizes = array_merge($sizes, $newsize);
	}
	return $sizes;
}

and if you like to redefine the whole thing and add new sizes :

can you please post the whole syntax error – there must be a path behind – isn’t it ?

Fixing the “Parse error: syntax error, unexpected T_FUNCTION” Error

There are multiple ways in which you could fix the “Parse error: syntax error, unexpected T_FUNCTION” error. We’ll explore the different methods here, but first, let’s discuss the actual origin of these errors. Basically, the T_FUNCTION error appears whenever there’s some syntax errors within your plugin or theme files. It can either be a non-valid part of your code, or alternatively the plugin or theme is trying to use features of a more advanced PHP version than the one actually installed on your server.

what php Version is running on your system

And – if you don’t like to determin for each page a background-image – and you can live with a slider – there will be with the same setup a plugin which handels the background.
See testpage – on every refresh there will be a new background ( the other pages are not adopted to that layout)

each image here : click to enlarge

1) use the stretched layout on enfold.
2) logo and navigation on top
3) header: logo left menu under it
3a) Footer: dont display footer nor socket
4) header-behavior : i have taken: Let logo and menu position adapt to browser window and sticky header
5) goto Layout Builder and mark : “Show element options for developers”

6) now we had to obtain your very small content
6a) for each page you have to have that layout here:

6b) and the grid gets this:

7) now the css for quick css

.responsive body {
    background-repeat: no-repeat;
    background-size: cover;
    background-color: transparent;
    height: 100vh !important
}
.responsive body.page-id-211 {
    background-image: url(path-to-your-image);
}
#header {
    width: calc(100% - 60px) !important;
    background: transparent;
    top: 30px;
    margin: 0 30px;
}
.html_stretched #wrap_all {
    background-color: transparent !important;
}
#main {
    background-color: transparent !important;
}
.main_color, .main_color .site-background {
    background-color: transparent;
}
.header_bg {
    opacity: 0.8 !important;
    filter: alpha(opacity=80) !important; 
}
.notfullsize .flex_cell.with-background {
    background-color: rgba(255,255,255,0.9) !important;
}
#av-layout-grid-1 {
    margin-bottom: 100px !important;
}

@media only screen and (max-width: 768px) {
.responsive #top #wrap_all #header {
margin: 0 30px !important;
}
}

you see here on that css that you can now have for each page a different background-image

.responsive body.page-id-211 {
    background-image: url(path-to-your-image);
}

to have now not a fullwidth grid-row insert this to your functions.php of your child-theme:

function grid_layout_notfull(){
?>
<script>
(function($){
    $('.av-layout-grid-container.grid-notfull' ).wrap( '<div class="main_color notfullsize"></div>');
    $('.notfullsize').css({"clear": "both", "width": "100%" , "float": "left" , "position": "static" , "min-height": "100px" });
    $('.grid-notfull').css({"max-width": "1310px", "margin": "0 auto" , "padding": "0 30px"});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'grid_layout_notfull');

if you need further assistance – your welcome
if you have done it send me a link to fine tune it

if this is what you like to have – i tell you how to reach it.

no – if someone has a bit of html knowledge it is not possible to hide it.

What do you want to achieve with this ?

Enfold offers something “to better reflect your own branding” via filter LINK

/** All of the Styling options you set in the theme’s Styling options get saved to a file in your uploads folder called enfold.css.
If you have changed the theme name or something like that you may want to re-name this file to better reflect your own branding. You can use the following function to do just that: */

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

hr.php : by the way the code has been changed a bit since 4.2.4
and the folder-structure too. so now hr.php is in a subfolder called hr.

See new download for hr.php since 4.2.4 here: https://webers-testseite.de/edited-enfold-alb-elements/#hr-with-id

both will work – just add the color for the font to Rikards code

can you send me the url where this is happening. If you don’t like to make it public.
Send me an e-Mail. My nick has all infos on that – leads to my homepage

Die Kommentare sind nicht beleidigend. Mein Hinweis auf das Verändern der Sonderzeichen in Code hätte eigentlich diesen Thread hier beenden können. Ob es ein Bug ist oder nicht sei einmal dahingestellt.
Die Leute hier geben sich alle Mühe Hilfestellungen zu geben. Diese Immer und Sofort einzufordern zeugt von einer gewissen Intolleranz auch den Anderen gegenüber – welche auch Hilfen erwarten.
Die meisten meiner Kommentare hier an Board versuchen anderen zu helfen, und das obwohl ich nicht Moderator hier an Board bin. Nahezu 3000 Antworten hier an Board zeugen gewiss nicht von Unfreundlichkeit sondern von Hilfsbereitschaft.

Ich hoffe daran zu denken, nicht mehr auf Anfragen deines Nicks zu reagieren. – Versprechen kann ich es nicht. Ich bin so erzogen hilfsbereit zu sein.

Sorry this is google translator:

The comments are not offensive. My reference to changing the special characters in code could actually have ended this thread here. Whether it is a bug or not is once left out.
The people here are trying hard to help. This demand always and immediately testifies to a certain intolerance to the other – which also expect help.
Most of my comments here on board are trying to help others, even though I’m not a moderator on board. Almost 3000 answers here on board certainly do not testify to unkindness but to helpfulness.

I hope to remember not to respond to requests from your nick. – I can not promise it. I am so educated to be helpful.

no comment on that:

even this board soft althought it is in code tags will transform some entities because they are starting with those signs like &:
