It is recommended that you should always upgrade your copy of WordPress whenever they release a new version because the new versions carry critical patches and may too have many new features that you can use to your advantage. For instance, the latest version (WordPress 2.3) takes care of the duplicate content problem (look under Canonical Redirection) that causes SEO woes for many webmasters and bloggers. I’ve been trying to tweak my .htaccess file to solve this but my blog wouldn’t load. I left it as it is then. Now I’ll upgrade to the latest version and see if it solves the problem.
Upgrading to the latest WordPress version is not as big a problem as it seems and even if you don’t know what folders to change and what not to change, you can easily do the following steps to upgrade your copy of WordPress.
- Take your database backup. Since WordPress uses MySQL you can use PHPMyAdmin to take you backup, or you can use any of the plugins available: I guess you should already have the plugin.
- Download the latest version of WordPress and unzip it to a folder.
- From there, delete the wp-content folder and wp-config.php file.
- Upload the entire thing to the remote folder that has your WordPress installation.
- Run http://www.yourblogname.com/you-blog-folder/wp-admin/upgrade.php
This should seamlessly upgrade your WordPress installation.
