Hey Manel,
Thank you for your patience, the taxonomy name would be a category, portfolio items are a post type.

Hey block4,
Try going to Enfold Theme Options ▸ Header ▸ Extra Elements ▸ No Phone Number/Extra Info

Hey seomar,
The white bar at the top was due to your LayerSlider having a space above the background image, I changed the background to “cover” and now it is fixed:

To have a different logo on mobile, Try adding this code to the end of your child theme functions.php file in Appearance ▸ Editor:

add_filter('avf_logo','av_change_logo');
function av_change_logo($logo)
{
    if(wp_is_mobile() ) {
    $logo = "http://kriesi.at/wp-content/themes/kriesi/images/logo.png";
    }
    return $logo;
}

change the url to your new logo image
The reason your LayerSlider is not showing until someone interacts wih it is due to your WPRocket lazy load, you need to add a exclusion

Your EWWW Image Optimizer is also dong the same thing:

I added these for you please clear your browser cache and check, if you still have trouble clear your server cache or disable both plugins.
for your last question, do you mean this:

it is in your LayerSlider, please change there.

Best regards,
Mike

Hi,
When I check your site I see four portfolio categories:

Hi,
Thank you for your patience, please try following these steps, first add a caption to your featured image in the media library:

Then add this css to your child theme stylesheet or the theme option Quick CSS:

.single-post .single-big a:after {
    content: attr(title);
}

and the caption should show like this:

Best regards,
Mike

Hi,
When I check your search fits well between the logo and the cart icon:

your css is for screen sizes starting at 990px and above, I guess you could rewite the css for other screens sizes, try modeling the css above for the screen size that you want to change.

Best regards,
Mike

Hi,
You can try and since most of these you are not using on your site you can disable them at Enfold Theme Options ▸ Performance ▸ Disable Template Builder Elements

Blue means that it is disabled, you should see text next to the button unused or in use to help you so you don’t disable elements in use:

Best regards,
Mike

Hi,
Try adding the custom class larger-thumbnails to the magazine element that you are using on the page and then add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function custom_larger_thumbnails_script() { ?>
  <script>
(function($){
  $('.av-magazine.larger-thumbnails .av-magazine-entry img').attr('width', '180px');
  $('.av-magazine.larger-thumbnails .av-magazine-entry img').attr('height', '180px');
  $('.av-magazine.larger-thumbnails .av-magazine-entry img').attr('sizes', '(max-width: 180px) 100vw, 180px');
  $('.av-magazine.larger-thumbnails .av-magazine-entry .av-magazine-thumbnail').css({'height': '180px','width': '180px'});
})(jQuery);
</script>
  <?php
}
add_action( 'wp_footer', 'custom_larger_thumbnails_script', 99 );

Please ensure to copy the code from the forum and not an email notification so the symbols are not converted.

Hey Susan Desko,
Thank you for your patience, in order to register for the support forum the first step is to register here, I assume that you have already tried this, when I check your Purchase Code the check returns: ITEM PURCHASE CODE IS INVALID
perhaps your Purchase Code is incompete, I recommend checking again.
From your post above it sounds like you can not login to your account, if this is true then you will need to contact Envato because they are the only ones that can create licenses, we can not create or provide licenses and our system only checks with Envato if a purchase code is valid, we don’t have access to the Envato backend.

Best regards,
Mike

Hi,
Perhaps we will need to try a different solution, please remove the solution above.

Best regards,
Mike

Hey Pierre,
Thank you for your patience, unfortunately the theme doesn’t have this option, I did find that the Easy Accordion Pro has this feature as shown in this video There may be other plugins that offer shortcodes to do this I’m not sure.
If you would like to request this feature, the Dev Team has opened a new Github Feature Request for users to place requests and follow them as the Dev Team reviews them.

Best regards,
Mike

Hey williamslyd,
Can you explain more about what you would like to achieve, a caption under the featured image, or over the image like a overlay? Perhaps a mockup would help.

Best regards,
Mike

Hey robertbwc,
The thumbnails under the product image is added via the metabox in the edit page:

To add a video under the product image, this space is the product sidebar, so you can add a sidebar widget with a video, if you want this for only one product or a different video for each product the Widget Options plugin will allow you to select which product pages will show which widget elements

Best regards,
Mike
