Hey Jack Song,
You can update and we do not expect any issues, but some things to keep in mind, if you have a custom header.php or footer.php in your child theme, you should remove these first, as they have changed. After you update you can review the new version of these files and make copies with your customizations into your child theme. I recommend tring to find a different way to add your customizations without using these files, or you will run into this issue again in the future.
The same is for any custom elements that you have in your child theme. If your child theme only has a style.css & functions.php & screenshot.png then you are fine.
If you have added any custom code to any parent theme files, you should save the code as it will be lost when you update.
You will not be able to automatically update via the theme options, as Theme Forest has changed since your version, after you manually update you will be able to update via the theme options for future updates.
A good practice is to use your web host options to create a stagging site and update it first to ensure your site looks & works the same, and then update your live site. If you are not able to do this, at least ask your web host to create a full backup, including the database for a fallback just in case.
To update your version of Enfold you will need to download the latest installable WP version from your Theme Forest account and upload it to your WordPress ▸ Appearance ▸ Themes ▸ Add Themes ▸ Add New
after you choose the zip file and click install, you will see a This theme is already installed message because you are updating, you can continue,
then you will see the Theme updated successfully message.
After which you can go to your Theme Forest account and create a new Token for future automatic updates.

Best regards,
Mike

Hi,
The only way would be to try reinstalling the theme. If this doesn’t work please start a new thread and include an admin login for us to examine in the private content area. Your login would not be private in this thread, as it is not your thread.

Hi,
Thanks for the video, I see first that you used the classic editor to save the page and then you switched to the ALB editor on the same page and added more elements and saved again. Please note that this can cause issues. Please do not switch between editors, only use one editor per page. Also note that if a corrupt page is saved as a template it can not be repaired, you will need to remove the template and rebuild a new page and create a new template.
Was the page that you tried to add the template to also saved in both editors?

Best regards,
Mike

Hey Michael F,
You have the sidebar enabled on these pages, disable this in the settings for these pages, or try this css

.page-id-2971 #after_section_1,
.page-id-2974 #after_section_1,
.page-id-2978 #after_section_1 {
	display: none;
}

Hey Daniel,
Please see this thread: https://kriesi.at/support/topic/cve-2022-48285-on-jszip-3-6-0/#post-1470007
If you wish, you can request the Dev Team to consider this again on our Feature Request: https://github.com/KriesiMedia/Enfold-Feature-Requests/issues
Note that at the time the updated version was buggy and did not work as it should, perhaps there is a newer update at this time? The Dev Team would need to review though the Feature Request link above.

Hey Sebastian,
In your theme settings you had the Load jQuery In Your Footer option enabled, so you were getting a jQuery error. I added

window.addEventListener('DOMContentLoaded', function() {
...
});

To the script to correct this.

Hi,
Try this instead:

add_filter( 'avf_contact_form_autoresponder_mail', function( $mail_array, $new_post, $form_params, $form_obj ) {
    if ( ! isset( $mail_array['Message'] ) ) {
        return $mail_array;
    }

    $message = $mail_array['Message'];

    $separators = [ '<hr', '———' ];

    foreach ( $separators as $sep ) {
        $pos = strpos( $message, $sep );

        if ( $pos !== false ) {
            $mail_array['Message'] = rtrim( substr( $message, 0, $pos ) );
            return $mail_array;
        }
    }

    $pattern = '/<br\s*\/?>\s*(?:Ihre Nachricht|Anrede|Vorname|Nachname|E-Mail|Thema|Nachricht)\s*:?/i';

    if ( preg_match( $pattern, $message, $matches, PREG_OFFSET_CAPTURE ) ) {
        $mail_array['Message'] = rtrim( substr( $message, 0, $matches[0][1] ) );
    }

    return $mail_array;
}, 10, 4 );

Or this:

add_filter( 'avf_contact_form_autoresponder_mail', function( $mail_array, $new_post, $form_params, $form_obj ) {
    if ( ! isset( $mail_array['Message'] ) ) {
        return $mail_array;
    }

    $message = $mail_array['Message'];

    $separators = [ '<hr', '———' ];

    foreach ( $separators as $sep ) {
        $pos = strpos( $message, $sep );

        if ( $pos !== false ) {
            $mail_array['Message'] = rtrim( substr( $message, 0, $pos ) );
            return $mail_array;
        }
    }

    $pattern = '/(?:<br\s*\/?>)?\s*Ihre Nachricht\s*:?|<br\s*\/?>\s*(?:Anrede|Vorname|Nachname|E-Mail|Thema|Nachricht)\s*:?/i';

    if ( preg_match( $pattern, $message, $matches, PREG_OFFSET_CAPTURE ) ) {
        $mail_array['Message'] = rtrim( substr( $message, 0, $matches[0][1] ) );
    }

    return $mail_array;
}, 10, 4 );

Hi,
The issue is that newer versions of jQuery (1.9+) no longer support the old CSS selector syntax using bare # characters. We need to escape them properly. This is the updated code that I added to your site, I also changed the offset to match your header height.

function slow_scroll_to_anchor() { ?>
  <script>
(function($) {
  $('a[href*="#"]:not([href="#"])').click(function() {
    var width = $(window).width()
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
&& location.hostname == this.hostname) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        if ($(window).width() < 768) {
          $('html,body').animate({
            scrollTop: target.offset().top - 150
          }, 1000);
          return false;
        } else {
          $('html,body').animate({
            scrollTop: target.offset().top - 250
          }, 1000);
          return false;
        }
      } 
    }
  });

  // Executed on page load with URL containing an anchor tag.
  var hash = location.href.split("#")[1];
  if (hash) {
    var target = $('#' + hash);
    if (target.length) {
      if ($(window).width() < 768) {
        $('html,body').animate({
          scrollTop: target.offset().top - 150
        }, 1000);
      } else {
        $('html,body').animate({
          scrollTop: target.offset().top - 250
        }, 1000);
      }
    }
  }
}(jQuery));
</script>
  <?php
}
add_action( 'wp_footer', 'slow_scroll_to_anchor', 99 );
