 * I can no longer update WordPress. It appears as though the update-core.php was
   missing. I’ve reput it back in and now I’m getting this fatal error:
 * Fatal error: Uncaught Error: Call to undefined function wp_get_update_php_annotation()
   in /homepages/35/d654296717/htdocs/clickandbuilds/LuxiumDev/wp-admin/update-core.

   LuxiumDev/wp-admin/update-core.php on line 88
 * I’m using WP 5.1.4. Can someone provide a solution?

 * Try **MANUALLY** updating. [Download WordPress](https://wordpress.org/download/)
   again and unzip it, and use that to copy up. Access your server via [SFTP or FTP](https://wordpress.org/support/article/ftp-clients/),
   or a file manager in your hosting account’s control panel (consult your hosting
   provider’s documentation for specifics on these), and delete then replace your
   copies of everything on the server EXCEPT the wp-config.php file and the /wp-
   content/ directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings. (**
   NOTE: do not delete the wp-content directory or your wp-config.php file**). **
   Please read the [Manual Update](https://wordpress.org/support/article/updating-wordpress/#manual-update)
   directions first.**
 * **Backup: If you haven’t already done, always backup everything (including your
   database) before doing any actions, just in case something really goes wrong.
   You can never have enough backups! See [https://wordpress.org/support/article/wordpress-backups/](https://wordpress.org/support/article/wordpress-backups/)**
