You should always update WordPress to the latest version. When a new version of WordPress is available you will receive an update message in your WordPress Admin Screens. To update WordPress, click the link in this message.
There are two methods for updating – the easiest is the one-click update, which will work for most people. If it doesn’t work, or you just prefer to be more hands-on, you can follow the manual update process.
Going to the Dashboard > Updates screen. Once you are on the “Update WordPress” page, click the button “Update Now” to start the process off. You shouldn’t need to do anything else and, once it’s finished, you will be up-to-date.
One-click updates work on most servers. If you have any problems, it is probably related to permissions issues on the filesystem.
Manual update is more complicated than One-click update,you should check out the extended upgrade instructions before you update.
- Get the latest WordPress zip (or tar.gz) file.
- Unpack the zip file that you downloaded.
- Deactivate plugins.
- Delete the old
wp-admin directories on your web host (through your FTP or shell access).
- Using FTP or your shell access, upload the new
wp-admin directories to your web host, in place of the previously deleted directories.
- Upload the individual files from the new
wp-content folder to your existing
wp-content folder, overwriting existing files. Do NOT delete your existing
wp-content folder. Do NOT delete any files or folders in your existing
wp-content directory (except for the one being overwritten by new files).
- Upload all new loose files from the root directory of the new version to your existing wordpress root directory
NOTE – you should replace all the old WordPress files with the new ones in the wp-includes and wp-admin directories and sub-directories, and in the root directory (such as index.php, wp-login.php and so on). Don’t worry – your wp-config.php will be safe.
Be careful when you come to copying the wp-content directory. You should make sure that you only copy the files from inside this directory, rather than replacing your entire wp-content directory. This is where your themes and plugins live, so you will want to keep them. If you have customized the default or classic themes without renaming them, make sure not to overwrite those files, otherwise you will lose your changes. (Though you might want to compare them for new features or fixes..)
Lastly you should take a look at the wp-config-sample.php file, to see if any new settings have been introduced that you might want to add to your own wp-config.php.
Visit your main WordPress admin page at /wp-admin. You may be asked to login again. If a database upgrade is necessary at this point, WordPress will detect it and give you a link to a URL like
http://example.com/wordpress/wp-admin/upgrade.php. Follow that link and follow the instructions. This will update your database to be compatible with the latest code. You should do this as soon as possible after step 1.
Don’t forget to reactivate plugins!
f you have caching enabled, clear the cache at this point so the changes will go live immediately. Otherwise, visitors to your site (including you) will continue to see the old version (until the cache updates).
Your WordPress installation is successfully updated. That’s as simple as we can make it without Updating WordPress Using Subversion.
Consider rewarding yourself with a blog post about the update, reading that book or article you’ve been putting off, or simply sitting back for a few moments and letting the world pass you by.
Your update is now complete, so you can go in and enable your Plugins again. If you have issues with logging in, try clearing cookies in your browser.
