How to update WordPress

Version 2.9 of WordPress was released the other day. [And not long after that, version 2.9.1.] Here’s how to update your WordPress website.

1. Clean up the database:
   • Go to the Edit Comments section of your blog’s Dashboard and mark any spam comments as spam.
   • Check the list of Spam comments for any that are in fact genuine and retrieve them.
   • Delete the spam comments so they’re not clogging up the database.
   • If you use anti-spam plugins such as Spam Karma clean out any accumulated logs.
2. Back up the database, uploads, theme, config, and other files. ¹
3. Check for updates to the theme you use, and install as required.
4. Use the auto-update function to check for updates to plugins you use and apply as required.
5. Use the auto-update function to update the WordPress files.
6. Visit your blog’s Dashboard again. If you see a notice about upgrading the database, follow the on-screen instructions. Recent versions of the upgrade handle this step for you.
7. View your blog as a visitor would see it. Check for problems and unpleasant surprises. If something seems weird start your troubleshooting by disabling plugins.
