Hello,

This doesn’t happen on our side.
What theme version do you have? Have you installed many third party plugins?
Send us a link where this is running to visualize better the issue.

Best regards!

Hello,

I created a copy of your portfolio page and this does not happen. Please see here: https://grupavcanal.pl/testing
I see no issue in your page except the fact that you have many other third party plugins installed. I suggest you to try and recreate the page again.
Let us know if the issue persists.

Best regards!

Hello,

Sorry for the late reply.
Please go to file portfolio.php and find these lines:

<nav id="portfolio-filter" class="span12">
   <ul class="">
   <li class="filter active all" data-filter="all"><a href="#" class="filter active" data-filter="all"><?php _e('View All', 'codeless') ?></a></li>
     <?php foreach($cl_redata['portfolio_categories'] as $cat): ?>
         <?php $cat = get_term($cat, 'portfolio_entries'); ?>
         <?php if(is_object($cat)): ?>
   <li class="other filter"  data-filter=".<?php echo esc_attr($cat->slug) ?>"><a href="#" class="filter" data-filter=".<?php echo esc_attr($cat->slug) ?>"><?php echo esc_html($cat->name) ?></a></li>
         <?php endif; ?>
       <?php endforeach; ?>
    </ul>
 </nav>

Replace with this:

<nav id="portfolio-filter" class="span12">
   <ul class="">
   <li class="filter active all" data-filter="all"><a href="#" class="filter active" data-filter="all" onclick="return false;"><?php _e('View All', 'codeless') ?></a></li>
     <?php foreach($cl_redata['portfolio_categories'] as $cat): ?>
         <?php $cat = get_term($cat, 'portfolio_entries'); ?>
         <?php if(is_object($cat)): ?>
   <li class="other filter"  data-filter=".<?php echo esc_attr($cat->slug) ?>"><a href="#" onclick="return false;" class="filter" data-filter=".<?php echo esc_attr($cat->slug) ?>"><?php echo esc_html($cat->name) ?></a></li>
         <?php endif; ?>
        <?php endforeach; ?>
       </ul>
 </nav>

Let us know.

Best regards!
