WordPress 2.3 Download I just updated to version 2.3 from something very old (2.0.6 I think). The tables post2cat, link2cat, and categories were all deprecated. When the Sideblog plugin that powers my link blog tried to grab these everything went pear shaped. I grabbed the latest version of sideblog and reloaded my database backup and everything was fine. I should have turned off my plugins before upgrading as suggested.
