Getting admin-ajax 500 error while using LOAD MORE button in only one site.

  • The plugin works fine in all other sites where I am using it. But in one site hosted in DigitalOcean droplet – the Loadmore button is not working. It is stuck and showing Loading…, in console I am getting ajax-admin error 500.

    Here’s the wp-debug log – 

    [01-May-2021 06:12:01 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function mb_convert_encoding() in /var/www/html/wp-content/plugins/ele-custom-skin/includes/ajax-pagination.php:445

  thrown in /var/www/html/wp-content/plugins/ele-custom-skin/includes/ajax-pagination.php on line 445

    Can you please help on how to solve this?

    sudo apt-get install php7.4-xml
    sudo apt-get install php7.4-mbstring

    This did the work. Sharing as someone could benefit form this.

    Edit:
