    call_user_func_array() error, by papitah19


    Guys, I need help please!

    I’m currently getting this error: Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘wp_maybe_grant_install_languages_cap’ not found or invalid function name in /home/u252582271/public_html/wp-includes/class-wp-hook.php on line 300

    and I can’t login to the admin page. It was working well before I updated the wordpress version. Now, I can’t even login as admin due to this error.

    What to do?
