Hi,
Thank you for the feedback and the link to your site, I see that you are getting this error in your console: Uncaught ReferenceError: jQuery is not defined I believe this points to you having the Load jQuery in your footer setting enabled in your theme settings, so the script runs before the jQuery library is loaded.
To correct this you could disable the setting so the JQuery library is loaded in the head, but I assume you would prefer to not allow this so try this script instead, it will try to wait until after the DOM is loaded before running the script:

<script>
window.addEventListener('DOMContentLoaded', function() {
(function($) {
  $(document).ready(function(){
    function replaceElementTag(targetSelector, newTagString) {
      $(targetSelector).each(function(){
        var newElem = $(newTagString, {html: $(this).html()});
        $.each(this.attributes, function() {
          newElem.attr(this.name, this.value);
        });
        $(this).replaceWith(newElem);
      });
    }
    replaceElementTag('h3.av-masonry-entry-title', '<h2></h2>');
  });
}(jQuery)); 
 });
</script>

Hi,
I believe that if the SVG files were truly supported by WordPress then there would be no need to modify the $logo in Functions.php, I will submit this to the rest of the team to see if they have any suggestions.

Hey Rob,
Thank you for your patience and for the link to your site, I see your product image is missing the class lightbox-added it is hard to tell what the issue is without logging in, but please check that the Enfold Theme Options > Performance > Load jQuery in your footer is not activated.
Otherwise please include admin login in the Private Content area so we can be of more assistance.

Best regards,
Mike

Hey farzanahmed,
Thank you for your patience and the link to your site, but as I examine it looks like you have already found the solution.
Was there anything further you wanted help with this?

Hey oliverhutz,
Thank you for your patience, unfortunately not, you will need to actually remove it.

Hey Harold,
Thank you for your patience, and for the link to your site, the reason the script is not working is because the social icons are not in the main menu as expected, they are in the topbar, so to correct please remove your other scripts and use this instead:

function savvy_custom_mod_social(){
?>
<script>
(function($){
      var int = '';
      function a() {
          var isMobile	 = $('.av-burger-menu-main').css('display'),
              htmlString   = $('#header_meta .social_bookmarks').find('li a'),
              mobileMenu   = $('.av-burger-overlay'),
              socialString = [];
  
              if(isMobile == 'none') return;
              if($('.burger-social').length) clearInterval(int);
  
              htmlString.each(function() {
                  var socialClass	= $(this).parent('li').attr('class'),
                          socialItems = $(this).wrap('<li class="'+ socialClass + ' av-active-burger-items burger-social"></div>').parent().unwrap();
                  socialString.push(socialItems);
              });
  
              $(socialString).each(function() {
                  $(this).appendTo('#av-burger-menu-ul');
              });
      }
  
      $('#header').on('mousedown', '.av-main-nav-wrap', function() {
          int = setInterval(function() {
              a();
          }, 500);
      });
  
  })(jQuery);
  </script>
<?php
}
add_action('wp_footer', 'savvy_custom_mod_social');

Hey DIAZTORTILLAS,
Thank you for your patience, and for the screenshots, do you mean that the font is supposed to be in italics, or is in italics in error?
From your Custom Font Manager screenshot it looks like the original zip file also has a Macosx directory which is adding the fonts twice, please delete both of these, then extract the zip on your desktop and remove the unneeded directories and files, then zip again and upload.
I recommend trying to upload the one font you plan on using the most as a test, for example, Forza-Black, then put that in a zip file by itself Forza-Black.zip, and upload and test.
Typically the regular & italics are in the same ttf file for normal use, but you would have to use a font viewer to check.
You would not be using a function in this case.

Best regards,
Mike

Hey kwlodar,
Thank you for your patience, when you say:

change the site where it linking to

do you mean redirect to a different domain, or do you mean change the page on the same site?
To change the page on the same site please adjust the Theme Options:

If you want to change the url of the link only for the title, perhaps to a different domain, then try adding this code to the end of your functions.php file in Appearance > Editor:

function custom_script() { ?>
    <script>
(function($){
$(".main-title > a[href^='https://kriesi.at/themes/enfold/blog/']").prop("href", "https://google.com")
})(jQuery);
</script>
    <?php
}
add_action('wp_footer', 'custom_script');

In the above code you will note the class .main-title, this is added so any menu links to the page will not be changed, then the next part of the code is the title link you want to change, then the last part is the link you want it to be.
If you have any problems getting this to work then please link to the page and let us know where you want the link to point to.

Best regards,
Mike

Hi,
Thank you for the feedback and the link to your page, in this situation the page is using the boxed layout so the page is contained at the body div so the element can not brake out of this, you will need to change to the full-width layout and then contain the elements you wish to 1310px, such as the footer & header.
As for the box shadow, please add a custom class the to the 1/3 columns and change the css to reflect:

.custom-class {
box-shadow: 0px 2px 18px 0px rgb(0 0 0 / 30%);
}

Hi,
I see that you have this custom css in your /wp-content/uploads/so-css/so-css-enfold.css

div .flex_column {
  display: flex;
}

removing it will correct the layout

Mike

Hi,
Thank you for the feedback, in your latest test/screenshot I see that you didn’t add the custom class to the color section so the css solution I posted would work, such as the working example I linked to for the screenshot above.

In order to make the iframe full-width, the parent container needs to be adjusted, so your first option is to place it in a full-width element such as a color section and then set it’s container width to 100% and remove any padding & margin overriding the theme Layout & Dimensions

Please note that this has nothing to do with the width of the iframe, I’m talking about the container inside the color section.
If you are not going to use a full-width element such as a color section, and the iframe is going to be in a code block (preferably), then add this custom class to the code block element code-block-for-iframe and use this css:

.code-block-for-iframe {
	width: 100vw !important; 
        position: relative !important; 
        left: calc(-50vw + 50%) !important;
}

Please see the link to the working example below.

Best regards,
Mike
