Updating or making an upgrade WordPress version to the latest is important to ensure you get the best security and performance of your website. This is also a pretty regular maintenance task that you will do quote often as long as WordPress release its latest core file updates.
As you probably know WordPress is used widely and as such a majority of WordPress websites get hacked due to use of outdated WordPress core files, plugins, or theme.
WordPress developers actively maintain this CMS to fix bugs, updrage new features, and patch any security vulnerabilities on a regular basis. These changes are then released in a new WordPress version and will often appear as a notification on your WordPress dashboard.
To ensure that your website has the latest security patches, newest features, and the best speed and performance rates, you need to update it.
WARNING: The upgrade process will affect all files and folders included in the main WordPress installation. This includes all the core files used to run WordPress. If you have made any modifications to those files, your changes will be lost.
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.
If you are updating across multiple versions, follow the procedure at Upgrading WordPress – Extended Instructions
Back up WordPress
Before you get started, it’s a good idea to back up your website. This means if there are any issues you can restore your website. Complete instructions to make a backup can be found in the WordPress Backup.
Automatic Background Updates
For WordPress 3.7 and the latest verabove, you don’t have to do anything to apply minor and security updates. Most sites are able to automatically apply these updates in the background. If your site is capable of one-click updates without entering FTP credentials, then your site should be able to update from 3.7 to 3.7.1, 3.7.2, etc. (You’ll still need to click “Update Now” for major feature releases.)
One-click WordPress Update
WordPress has added the click of a button this is where you start the upgrade WordPress process. You can launch the update by clicking the link in the new version banner (if it’s there) or by 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.
WordPress determines what method it will use to connect to the filesystem of your server based on the file ownership of your WordPress files. If the files are owned by the owner of the current process (i.e., the user under which the web server is running), and new files created by WordPress will also be owned by that user, WordPress will directly modify the files all by itself, without asking you for credentials.
WordPress won’t attempt to create the new files directly if they won’t have the correct ownership. Instead, you will be shown a dialog box asking for connection credentials. It is typical for the files to be owned by the FTP account that originally uploaded them. To perform the update, you just need to fill in the connection credentials for that FTP account.
Whether your files are owned by the web server user, or not, will depend on how you installed WordPress and how your server is configured. On some shared hosting platforms, it is a security risk for the files to be owned by the web server user and not a FTP user. See the tutorial on Changing File Permissions for more information, including how to configure file permissions so that multiple FTP users are able to edit the files.
Failed Updates, Delete the file .maintenance
If you see a “failed update” nag message, delete the file .maintenance from your WordPress directory using FTP. This will remove the “failed update” nag message.
If the one-click upgrade WordPress doesn’t work for your website or blog, don’t panic! Just try the manual update, which is a but cumbersone and needs some experiece. We have writen a blog about here
Delete caching to view the latest updates and clap for yourself
It is important to clear any caches if f you have caching enabled. Clearing the cache will ensure that changes you have applied 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 thus 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.
Here is our blog about caching plugins
If anything has gone wrong, then the first thing to do is go through all the steps in our extended upgrade instructions. That page also has information about some of the most common problems we see.
If you run into a request for FTP credentials with trying to update WP on a IIS server automatically, it may well be a matter of rights. Go into the IIS Management Console, and there to the application pool of your blog. In its advanced settings, change the Process Model Id into LocalSystem. Then on Sites, choose your blog, right click, click on Edit permissions and on security tab add authenticated users. That should do it.
If you experience problems after the upgrade, you can always restore your backup and replace the files with ones from your previous version from the WordPress Update release archive.
