WP version for new feature

See this URL on your blog: https://acrosstrans.com/blog/wp-links-opml.php

You are running version 2.2.1 and should upgrade. See https://codex.www.ads-software.com/Backing_Up_Your_Database or https://codex.www.ads-software.com/WordPress_Backups and backup.

Once you are comfortable that your database and files are backed up, and you can restore them, them give https://codex.www.ads-software.com/Upgrading_WordPress this link a try.

If it fails, restore your backups and try again.

Good luck.

Thanks jdembowski.

Someone suggests me if I want to upgrade WP, I only install an auto-backup plungin to the database, it isn’t necessary to backup database relating to phpmyadmin.
