Wordpress site corrupted following upgrade

Username (e.g. epiz_XXX) or Website URL


Error Message

Essentially ‘white screen of death’, “an error ocurred site cannot be loaded”

Other Information

Upgrading to new Wordpress version did not complete
Debug mode is throwing up errors from Settings.php saying other .php files are missing (presumably new php files required in the new version that have not been installed)

Can you share a URL?
Thanks for enabling debug mode! But exactly what do the errors say?


These should be helpful


Thanks for the prompt replies :slight_smile:
Have have manually uploaded the new folders via FTP, but none of the HTDOCS files as yet. I now have a functional admin page with pages etc intact. But the website now gives me:

Fatal error : Uncaught Error: Call to undefined function wp_get_global_stylesheet() in /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/script-loader.php:2322 Stack trace: #0 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/class-wp-hook.php(307): wp_enqueue_global_styles(‘’) #1 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #2 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/plugin.php(474): WP_Hook->do_action(Array) #3 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/script-loader.php(2105): do_action(‘wp_enqueue_scri…’) #4 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/class-wp-hook.php(307): wp_enqueue_scripts(‘’) #5 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/class-wp-hook.php(331): WP_Hook->apply_filters(NULL, Array) #6 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/plugin.php(474): WP_Hook->do_action(Array) #7 /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/general-template.php(304 in /home/vol1_3/epizy.com/epiz_30569901/htdocs/wp-includes/script-loader.php on line 2322

There has been a critical error on this website.

Please upload all the files. A lot of those errors may be because the system cannot find the file.


Quite correct. I decided to continue with the top level files and once I selected a theme (20222) the site is alive. Many thanks!
