Support » Themes and Templates » Fatal error: Call to undefined function….themes

  • Hello,
    After searching for my specific fatal error I could not find a solution to the following:
    Fatal error: Call to undefined function list_category_posts() in /home/affil129/public_html/wp-content/themes/multi-traffic-warrior-theme/sidebar.php on line 21.

    All of this happened after I upgraded. I also did not backup any of my files before taking this action.
    My site disappeared and I am not sure what to do. I am a newbie and I am sorry if I sound rather inane, but please help.

    Thank you in advance

  • Do you have FTP access to your account? If so, FTP to your account and navigate to sidebar.php. Copy the code in that file to and add the past bin URL as a comment to your question here. I’ll take a look and hopefully get you back up and running.

    For more detailed instructions on see here:

    If you don’t have FTP access to your account contact your hosting provider.

    it seem your theme have an error, or it required some plug in called list_category_post().
    maybe the related plugin is , but iam not sure. or you can change list_category_post() to wp_list_category() 🙂

    or, you can just delete this theme (multi traffic warrior theme), reupload it or use another theme.

    Thank You so much for your help, I really appreciate it!!
    I contacted the company that built the site, and they reinstalled it for me. My problem was that I updated a plugin and everything went downhill from there.

    Thanks Again
