Warning: ksort() expects parameter 1 to be array

  • Hi! I had a big problem with my site (Hacker attack and delete ALL the site). So i had a backup from Nov 2016. I uploaded everything BUT Yarrp plugin has a this Warning:

    Warning: ksort() expects parameter 1 to be array, object given in /nfs/c03/h03/mnt/56037/domains/hambrientos.cl/html/wp-content/plugins/yet-another-related-posts-plugin/keywords.php on line 111

    That Warning appeared when i unchecked “Display related posts in feeds?” because i have the <?php related_posts(); ?> tag in single.php in the Theme.

    The page I need help with: [log in to see the link]
