Instructions on how to update your WordPress site using FTP mode:
- Open public_html folder using FTP mode. That is the root directory where wordpress CMS was installed.
- Pre-make a fresh copy of the database.
- Make a backup of all the files located in the root directory in the event if something goes wrong. As “WP-Content” folder can contain a lot of graphics and large files, as well as your current theme and customized plug-ins, it may remain uncopied. Remove the folder “wp-admin” containing the old version files and fill up with a fresh version in the same place in root directory (new version can be found on the official site).
- Delete this folder and refill it up as “wp-includes”.
- Delete all php files from root directory, except verification scripts for search engines, error logs and file “wp-config”, as it contains information about the site database and its main user. Upload there the files from the new version as well.
- Open your website in the browser. WordPress will ask you to update the database after the upgrade procedure. Click “upgrade”, and a new version starts functioning promptly. Run the admin panel then and check all major functions operability. Check site categories and plug-ins operation as well. In case some function does not work – look for a failure cause; perhaps in this version plug-ins should be updated.
- If something went wrong – restore your premade backups.
Congratulations! Now you have the latest WordPress version!
