You don’t need to add it by hand. * When we say to “manually reinstall”, we do mean that. As in, actually replace the files on the server with the correct ones. The wp-settings.php file in WordPress 4.5 changed. If you did only a partial installation, and did not update ALL the files, including those in the root directory, like wp-settings.php, then yeah, your site will remain broken. * MANUALLY UPDATE ALL THE FILES. That will fix this problem. * [mkmpvtltd](https://wordpress.org/support/users/mkmpvtltd/) * (@mkmpvtltd) * [10 years, 1 month ago](https://wordpress.org/support/topic/wordpress-45-error-after-update/#post-7274429) * hi there i have fixed my site instruction given by salj42 but when i want to access wp-admin there is problem like css not loaded(Page without design)? * [monica](https://wordpress.org/support/users/monilou/) * (@monilou) * [10 years, 1 month ago](https://wordpress.org/support/topic/wordpress-45-error-after-update/#post-7274438) * Not sure if I should start a new thread??
