Hi,
I added this css:

.avia-menu>ul.av-main-nav li.menu-item-top-level:not(#menu-item-287) {
    flex-grow: 1;
}

this added the flex-grow to every item except the last one giving us the trouble, I don’t think that it is noticeable because it’s a longer text length and it’s at the end, but this solves the other two issues.
Please clear your browser cache and check.

Hi,
I recommend reaching out to the original developer and ask them to convert your custom named theme into a official Enfold named theme so the updates will work.
Since there is a update available, this is a good time for them to do this.
the text string in your URL looks like a cache version, so it sould be from your cache plugin or your server cache, I’m not sure, but this was not there the last time I checked so I’m not sure what changes you have made. I don’t want to “tinker” with it while you are in the process of contacting the original developer. As I pointed out earlier your custom site has custom code that I don’t understand so my “tinkering” could do more harm that good.

Hey Diana,
Thank you for the link to your site and the screenshots, some of them didn’t work, so as I understand this text link on your homepage is not landing correctly for you:

it is meant to land on a empty color section:

when I test it lands correctly, the blue in this screenshot is your empty color section:

I tested with Windows in Chrome & Edge and Mac in Safari & Chrome, and all worked correctly, only Firefox on both Windows & Mac didn’t work correctly, I’m not sure why firefox is having an issue, but to try to adjust for the firefox error I added this code to your functions.php:

function custom_smooth_scroll_to_id_for_firefox_script() { ?>
  <script>
function slowScrollToAnchor() {
  var urlHash = window.location.hash;

  if (urlHash) {
    var target = document.querySelector(urlHash);
    if (target) {
      var targetPosition = target.offsetTop;
      var startPosition = window.pageYOffset;
      var distance = targetPosition - startPosition;
      var duration = 1000;
      var startTime = null;

      function scrollAnimation(currentTime) {
        if (startTime === null) startTime = currentTime;

        var timeElapsed = currentTime - startTime;
        var scrollY = easeInOutQuad(timeElapsed, startPosition, distance, duration);
        window.scrollTo(0, scrollY);

        if (timeElapsed < duration) {
          requestAnimationFrame(scrollAnimation);
        }
      }
      function easeInOutQuad(t, b, c, d) {
        t /= d / 2;
        if (t < 1) return c / 2 * t * t + b;
        t--;
        return -c / 2 * (t * (t - 2) - 1) + b;
      }

      requestAnimationFrame(scrollAnimation);
    }
  }
}

window.addEventListener('load', slowScrollToAnchor);
</script>
  <?php
}
add_action('wp_footer', 'custom_smooth_scroll_to_id_for_firefox_script', 99);

and after clearing your site cacke and my browser caches for all of my test browsers the anchor link is now correct, even in Firefox. Most of my tests landed correctly even on firefox, but in one case on firefox the script scrolled the page backwards to land in the land place. So the script shows to correct the issue.
If you want to adjust the one second delay you can change var duration = 1000; to a higher or lower number 1000 equals one second, it seem to work good just the way it is.

BTW – your Header Footer Code Manager plugin don’t seem to allow PHP snippets, so if you are not going to use a child theme I recommend the WPcode plugin this plugin supports PHP code snippets, JavaScript code snippets, & CSS code snippets.

Hi,
It sounds like your page has some broken elements due to some unclosed tags, typically this occurs when “strong” tags are added to title fields and the closing tag is missing, or when div tags are added the closing tag is missing. This can occur when text is copied and paste into a text element in visual mode. Try checking the text elements in the “text” mode to see if there a added div tags. If you see any elements with a red warning, please follow the link in the warning and remove the HTML code:

Sometimes a page with these errors can not be fixed and a new page will need to be created. If your page has these kind of errors please try creating a new page without these kind of errors and see if this solves your issue. Please note that if you have used templates from saved elements or pages, these may include the broken code and will need to be removed as they can not be fixed, so try to create your page from scratch and see if you can reproduce the error, if you can and you have already tried to disable all of your plugins to ensure there is no plugin conflict, then please link to your test page so we can examine and try to reproduce the error.

Is is correct, and the Enfold Theme Options ▸ Performance ▸ Responsive Images And Lazy Loading ▸ Lazy Loading sets the blog post featured images.

Hi,
Try this CSS in your Enfold Theme Options ▸ General Styling ▸ Quick CSS field:

.main_color .sidebar .produktfilter > h4 {
    color: #fff;
}
.sidebar .facetwp-facet {
    margin-bottom: 0;
}

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.
After applying the css, please clear your browser cache and check.

Hi,
Thanks for your patience, I disabled the script above and added a new mega menu column item call “new item” this makes the mega menu show correctly and the sub-menu items work when you click them, please try to use this new column in your mega menu, changing the name and link to something you can use.

Hi,
The ones that begin with “av_alb_usage_av_” are from the theme, in your screenshot most of yours are from the mailpoet plugins and from the core wordpress, I can’t recommend disabling any of those. When I check my site I only see 110 that start with av_alb_usage_av_ one for each element as in this post.
To address your 502/504 errors first try to disable all of your plugins and then test them one at a time to find what is causing the errors. I would also recommend improving your server settings and not disabling the autoload options, because doing so will cause your site to increase the number of database queries which will slow that function of your site down.

Best regards,
Mike
