    I brought the site live from a local computer with all in one migration. After the move, the home page turned white.

    Even if I set debug to wp-config.php file to true it doesn’t show error message.

    When I connected with ftp, I saw the “error_log” file and it says the following error code inside:

    [21-Feb-2020 20:07:49 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function flatsome_html_classes() in /home/u9276536/public_html/wp-content/themes/akgun-grup/header.php:2

    That first line tells you everything
    Call to undefined function flatsome_html_classes() in /home/u9276536/public_html/wp-content/themes/akgun-grup/header.php:2

    Your theme’s header.php is calling a function flatsome_html_classes on line 2 that does not exist.
    Maybe you didn’t copy the entire theme in the migration?
    Find that function and make sure it is in the theme. If you can’t, you need to log in and switch themes.
