Upgrades for WordPress 2.0.10 (latest pre-Ella version) and WordPress 2.1.3 (latest Ella version) have been released and you should grab them here. WordPress notifies you of updates available via the RSS feed on your WP dashboard. You should develop the habit of applying those upgrades as soon as they are available to keep internet nasties at bay and to improve functionality. (Most upgrades are bug fixes, but quite a few of them patch security holes and those are the ones you definitely want to have.)

Once you’ve upgraded a few times, you’ll find you can do it in your sleep. So, what are you waiting for. Let’s upgrade that WordPress site!

1 BACKUP YOUR MYSQL DATABASE. This can be done either via the WP Backup utility (plugin) in the WP Dashboard or via PHPMyAdmin. (This is not a necessary step; I’ve NEVER had database failure during an upgrade, but I’d do this if I were working on your site just as a matter of good business practice: It’s not nice nor is it good for my reputation to blow up client sites!)

2 Make copies of any files you’ve customized. Most folks have just customized their themes, so you shouldn’t have anything to worry about there. If you’ve customized a plugin, be sure to FTP it to your hard drive or otherwise make a copy of it (rename it on the server, for example, unless it is in a file that is destined to be nuked later in this procedure such as wp-admin or wp-includes).

3 Login to your blog and disable ALL plugins.

4 FTP into your site and delete the following:

• All *.php files in the WP root EXCEPT .htaccess and wp-config.php, OR ANY CUSTOMIZED OR RENAMED FILES (see Item 2 above).
• /wp-includes folder/directory
• /wp-admin folder/directory

5 Download the latest upgrade distro from the WordPress site here: http://wordpress.org/download/

6 Unzip the contents of the distro file.

7 FTP to your site and upload the folder contents to your site. (Be careful not to upload any .htaccess or wp-config.php files because you don’t want to overwrite what’s already there.

8 Login to your WordPress blog and point your browser to upgrade.php, in the wp-admin folder/directory (example follows):
http://www.yourcooldomain.com/wp-admin/upgrade.php

9 Follow the steps there and the upgrade is complete.

10 Next, go to your Plugins page and reactivate each plugin ONE AT A TIME, checking your site after each activation. If there is a plugin that breaks the site or you are confronted with a blank page after its activation, this usually means that plugin is not compatible with this latest version of WordPress. At this point you have two options: Disable the plugin and find a compatible plugin with the same or similar functionality, or contact that plugin’s author/developer to see if a newer version of the plugin is in the works. Check the WordPress site for a comprehensive list of WP 2.0.x compatible plugins.
