    When I go to my website, it returns this error:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wp_widgets_init’ not found or invalid function name in /public_html/wp-includes/plugin.php on line 503

    what could be causing this?

    What did you do before this issue happened? For example:
    – Did you update WP? Yes? Was it auto update or manual update? Also, updated from what version?
    – Did you install/update plugins?
    – Did you install/update theme?
    – What theme are you using currently? Where did you download ir from?
    – Are ALL your plugins and the current theme up to date?
    – Have you moved your site to new server, new domain, or new directory
    – Did your site work without any issue before (No hacking, no error, etc.)?
    – Have you checked your server error logs?
