How to Update to WordPress 4.0.1: Security Release

How to Update WordPress

WordPress 4.0.1 is now available. This is a critical security release for all previous versions and we strongly encourage you to update your sites immediately.

Sites that support automatic background updates will be updated to WordPress 4.0.1 within the next few hours. If you are still on WordPress 3.9.2, 3.8.4, or 3.7.4, you will be updated to 3.9.3, 3.8.5, or 3.7.5 to keep everything secure. (We don’t support older versions, so please update to 4.0.1 for the latest and greatest.)

WordPress versions 3.9.2 and earlier are affected by a critical cross-site scripting vulnerability, which could enable anonymous users to compromise a site. This was reported by Jouko Pynnonen. This issue does not affect version 4.0, but version 4.0.1 does address these eight security issues: For more details, click here.

WordPress Updating Tips

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 changes to those files, your changes will be lost.

IMPORTANT

As noted above:

If you are still on WordPress 3.9.2, 3.8.4, or 3.7.4, you will be updated to 3.9.3, 3.8.5, or 3.7.5 to keep everything secure. (We don’t support older versions, so please update to 4.0.1 for the latest and greatest.)

To get on the latest and greatest — if you are that far behind know your site is vulnerable and the sooner you get on 4.0.X the better!

when updating WordPress themes or plugins following the simple steps below can save you some headaches. Being this is a version update, double-check with your theme’s developer *before* updating to see if they have any concerns or comments about your theme and this new version. If you are on a quality theme your developer will be on top of this.

Step-by-step instructions to help you safely and easily update to the most recent version of WordPress.

Before you update we need to do a little housekeeping:

  • Save a copy of all your WordPress files, pages and posts to your hard drive. You do this by clicking on the Tools icon in the left sidebar and then Export. On the next screen click on Download Export File. You might want to create a new Folder on your hard drive where you keep all your Website files. Name it WP Backup so you know to save all backup files for WP there (and you’ll know where to find them if you need them). It is a good idea to back up this file once a month anyway regardless if an update is needed.
  • Backup your WordPress database. There is a nifty plugin that makes this process a no brainer, WP-DBManager. This plugin is also a must have for repairing and optimizing your database (which you should be doing minimally monthly to keep things running smoothly).
  • Do a quick double-check with your framework/theme developer to see if there are an issues with their themes and the most recent WordPress update. Same goes for your plugins. The last thing you want to do is update WordPress to find out after the fact your theme or plugins have conflicts.
  • Cover all the bases and download your theme/framework/child theme folders to your local hard drive. This is just good practice if you have customized any theme files.
  • To be safe, deactivate all plugins before upgrading.

It is a good idea to Review my article:

Once you get the above tasks accomplished, follow the links in the nag bar (it’s called a nag because that yellow bar will be up there “nagging” you until you take care of the important issue noted) and update your site to the latest version of WordPress.

Then, don’t forget to reactivate and update your plugins. You’ll see with each WordPress update that plugin developers also update their plugins which you can also do with one click. You’ll see the now familiar yellow nag bar under the plugin name in the plugins area with a link to “upgrade automatically.”

If you find after an update that something is not working as it was, go through the systematic process of deactivating your plugins one at a time until you find the culprit. If the developer has not updated his/her plugin to work with the lasted update, find another plugin whose developer is on top of these things.

Updating should not be ignored or put off. When you keep up with WordPress, have a Premium Theme and Plugin updates, you are not only keeping up with technology, but you make sure your site is secure and functioning error free.

At your service,
