Hi,
at http://spo-developments.com/our-portfolio/ you put portfolio with 4 columns.
Please go to you page-portfolio-4columns.php (you can find it here \wp-content\themes\dzen)
and find this code(it should be on line 78):
$out.= '<div class="portfolio_item portfolio_item_4' . $slugs . '">
<div class="overlayed">
' . get_the_post_thumbnail() . '
</div>
</div>';
Replace that code with this:
$out.= '<div class="portfolio_item portfolio_item_4' . $slugs . '">
<div class="overlayed">
' . get_the_post_thumbnail() . '
<a class="overlay" href="'.get_permalink().'">
<p class="overlay_title">' . get_the_title() . '</p>
<p class="portfolio_item_tags">
'.$in_category.'
</p>
</a>
</div>
</div>';
If this doesnt’t work please send us your FTP so we can fix it.
As we see at homepage all work good, you can see at picture in attachment.
I hope this help you.
Kind regards
