maybe it is just the fact that the new WP 6.7 switches back to block editor as standard.
Goto Enfold – Theme Options – Select your Editor : and switch back to classic Editor.

or is the problem that you want to use the block editor – but had no enfold elements anymore?

By the way. I can see the button at the top to activate the advanced layout editor – but the active click area is only on the half right. (as if only this part of the standard editor button area is active)
It is that field on the left that overlaps the Enfold button.

______________
not necessary:
it starts with ALB editor even in Block Editor Mode if you got this in your child-theme functions.php:

function trigger_alb_on_load(){
?>
<script>
(function($){
    $(window).on('load', function(){
      setTimeout(function() {
        $("#avia-builder-button").trigger('click');
      }, 300);
    });
})(jQuery);
</script>
<?php
}
add_action('admin_head-post-new.php', 'trigger_alb_on_load');

As a participant as you i can not see private content – may we others see the page it concerns?

Which icons are affected? The normal entypo-fontello icons or individually uploaded icon fonts?

First : how about your WordPress Version – does it need an update too?
if there is a big difference – a major Update in WordPress too … make a Backup of your Installation – and maybe prepare your theme allready for that newest WP – see: Unfortunately, the theme is no longer set as sticky regarding the adaptation to newer php versions / WordPress versions. But that is not necessary and can be done afterwards
What php Version you are running on your system – there are a few changes that need to be taken into account. Especially the changes from php7.x to php8.x and the implementation of jQuery 3.x …

I have never had any problems with WPML updates and Enfold updates. However, I agree with you that plugins that interfere with many areas of a theme always carry update risks.
That’s why I already have a good backup plugin installed for most sites for other reasons. Even the free version of Duplicator is a very good program.
This program creates a complete backup in two files. A zip file with the contents, and an installation file for restoring the backup. Btw. this can also be used for migration.
So if major updates are planned, I create a Duplicator backup beforehand and can then make the updates without losing the status quo.

________________

Updating the theme – additionally you can update the theme by ftp upload : https://kriesi.at/support/topic/some-hints-and-advice-to-update-enfold/#post-1056107

Uploading the new theme takes a little time; if all goes well, the page will only be offline for the small amount of time that it will be renamed. You have the old installation as fallback. (there is no overwriting of the old theme)

Update via ftp.

• download installable newest Enfold : unzip the file – you will have an enfold folder now
• Rename that downloaded newest version to enfold-new
• Upload that enfold-new folder to the themes folder
• Rename your (existing) enfold folder to f.e. enfold-old / in your ftp client (f.e. filezilla)
• Rename your enfold-new folder to enfold / again: in your ftp client (f.e. filezilla)
• Go to dashboard – enfold(-child) – and refresh your merged/cached files on performance tab
• Check if all your theme and existing settings work to your full satisfaction.
• Yes – then stop here

• No – delete or rename back the enfold folder back to enfold-new
• rename the enfold-old folder back to enfold

there is a lot of inline code to handle the toggler ? why?

For my part, I find it confusing that the open toggle moves to the top. For example, I have a plugin, pageScroll2ID, which unfortunately wanted to do the same thing. Fortunately, I was able to exclude the toggles from that behavior.

sorry:

function my_text_strings( $translated_text, $text, $domain ){
  switch ( $translated_text ){
    case 'Suchergebnis nicht zufriedenstellend? Versuche es mal mit einem Wort oder einer anderen Schreibweise'   :  $translated_text = __( 'Versuche es mit einem anderen Suchbegriff', $domain ); break;
  }
  return $translated_text;
}
add_filter('gettext', 'my_text_strings', 20, 3);

ja – wenn du dir die Lang Files ansiehst, ist im de_DE_formal.po und im de_DE.po die gleiche Übersetzung dafür vorgesehen.
Entweder bearbeitest du jetzt diese Langfiles und lädst Child-Theme Lang files hoch, oder du nutzt Plugins um solche Dinge verändern zu können.
Wenn es nicht allzuhäufig vorkommt kannst du diese Übersetzung auch via snippet in der child-theme functions.php ändern:

function my_text_strings( $translated_text, $text, $domain ){
  switch ( $translated_text ){
    case 'If you are not happy with the results below please do another search'   :  $translated_text = __( 'Hier jetzt deine neue Übersetzung hinein', $domain ); break;
  }
  return $translated_text;
}
add_filter('gettext', 'my_text_strings', 20, 3);

You have changed the minimum height of #header_meta – haven’t you? You now have to increase the padding-top for #main for non-transparent pages by this amount (difference from the default 30px to the new value).

f.e.: depends on your hamburger break point

@media only screen and (min-width: 990px) {
  .html_header_top.html_header_sticky #top #wrap_all #main {
    padding-top: 220px;   /*** have a look what your default value is on that + difference of new #header_meta ****/
  }
}

PS: just a moment i have to look how it is about for non-sticky headers.
best is to see the page to give better advice.

hm – isn’t it part of that css i gave to you? https://kriesi.at/support/topic/hamberger-menu-trigger/#post-1470941

because i got three ID’s as well inside that rule – it should work without !important too.

ps – on mobile phones with less then 375px width (protrait mode) the search drop-down window has a lot of space on the right and is nearby the left side. you can shift that window.
Add inside the media query above:

  /*** if you like to shift the search drop down window ***/
  /*** insert to the media query above that additional css ***/

  #top .avia-search-tooltip {
    top: 95% !important;
    margin-left: -70px !important;
  }
  #top .avia-search-tooltip .avia-arrow-wrap {
    right: 60px !important;
  }
  .avia_mobile #top #searchsubmit {
    height: 39px !important;
  }

try to hamper it first by going to :
Header – Extra Elements – Enfold WPML Language Flags (Global Setting)
If they will be shown – then look to
WPML – Languages – Menu language switcher

it they still are shown try:

function avia_remove_main_menu_flags() {
	remove_filter( 'wp_nav_menu_items', [ avia_WPML(), 'handler_append_lang_flags' ], 9998, 2 );
	remove_filter( 'avf_fallback_menu_items', [ avia_WPML(), 'handler_append_lang_flags' ], 9998, 2 );
}
add_action('init','avia_remove_main_menu_flags', 9999);

open automator application:
Select Application

then choose on the left side – “Files and Folders” – “Create Archive” – double click – then you have on the right side the options for it.

Next: choose on the left side “Utilities” and then “Run Shell Script – double click (or drag and drop to right side)

erase the pre set content and insert:

zip -d "$@" "__MACOSX/*" || true
zip -d "$@" "*/.DS_Store" || true

pay attention to have it “as arguments”

Save that on your desktop ( close it will ask yor for a name )

now you got an icon on your desktop like:

you drag&drop now your files/folders to it to have zip-files without those annoying hidden system files

and command line means using : terminal
Btw: the __MACOSX had to be ignored too.

can you test it:
but if you know how to create an automator script you can have a drag&drop symbol on your desctop to zip without any hidden OSX file.
on default it will create a zip file with same name as the object ( folder or file ) – but it will ask you to enter a filename. Let the mark on

you can download that little program on : https://webers-testseite.de/zip-it.zip

Can you download it – and test it – because on all docus about automator it says that this method will exclude hidden osx system files ( not the hidden files)

Edit : oh sorry did not see that your masonry is a image gallery.
But the sorting list did not exist on image masonry galleries at all.

_______________
if you follow ismaels proposal then you can show the masonry element by tag.
you then can set for each of your post/portfolio a tag (color) and sort these entries – then by tag.

PS if you got posts and portfolios with the same tag – they will be shown side by side.

see example page again
https://webers-testseite.de/masonry-blog/
– but did this for now only for that page. Not coming from a different page. From different page it first starts with all sorting.

However, in my opinion, the decision to place the sorting near the masonry makes more sense than the navigation solution.

function transfer_click_to_sort_options() { 
?>
<script type="text/javascript">
window.addEventListener("DOMContentLoaded", function () { 
	(function($){
		$('.sort .sub-menu a').click(function() {
			var linkPath = $(this).attr('href');
			var linkHash = linkPath.split('#')[1];
			$('#top').find('.av-sort-by-term a[data-filter="'+ linkHash +'"]').trigger('click');
		});
	})(jQuery);
});
</script>
<?php 
}
add_action('wp_footer', 'transfer_click_to_sort_options');

create your main menu with individual links – link is the page with your masonry and that hash value of the sorting. (the data-filter on the sorting are built by NAME_sort and for all it is all_sort)
to better select the first level domain i give a custom class to (Sorting) : sort

i have no solution of coming from a different page to open the masonry directly with that sorting.
