As per usual, this means we’ll start preparing for the Master List we generally provide for every major release A set of releases or versions having the same major version number may be collectively referred to as “X.Y” -- for example version 5.2.x to refer to versions 5.2, 5.2.1, and all other versions in the 5.2.

For reference, you may view the WordPress 4.9 Master List (formerly known as the “OMGWTFBBQ” thread, but that term didn’t mean much to users, so we simplified it).
Notable exclusions is the 2nd reply, noting “Core Core is the set of software required to run WordPress. The Core Development Team builds WordPress. changes”, as the release is all about one feature this isn’t needed.

The Troubleshooting Section
Before posting, please make sure you’ve tried started by performing the troubleshooting steps outlined below:
- Flushing Managed host caches. Managed WP hosting often has special caches. If your host has a “Purge Varnish” or “Flush Memcache” tool, try that. You can ask your provider to flush memcache and Varnish for you if necessary.
- Deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.

If you can’t get into your admin dashboard, try resetting the plugins folder by SFTP/FTP or PhpMyAdmin (read “How to deactivate all plugins when you can’t log in to wp-admin” if you need help). Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to

- Manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 4.9 (top right on this page) to your computer, and use that to copy up. You may need to delete the wp-admin and wp-includes folders on your server (NOTE: do not delete the
wp-content directory or your
wp-config.php file) Read the Manual Update directions first.
