Introduction

If your WordPress comment counts got messed up, whether because of a plugin (I'm talking about you, DISQUS) or you messed with your database manually and did something wrong (yup, that's what I just did), fear not – I have a solution for you.

But first, a little background.

Comment Counts In WordPress

Here's how comment counts work in WP:

• Posts live in a table called wp_posts and each has an ID.
• Comments reside in a table called wp_comments, each referring to an ID in wp_posts.
• However, to make queries faster, the comment count is also cached in the wp_posts table, rather than getting calculated on every page load.

On Friday afternoon, I went to give a presentation about MySQL advanced features at the Sardegna Ricerche technology park. The presentation included a quick introduction to MySQL Sandbox, something that I have been doing for years, and I thought I could do blindfold, if required. However, something didn't go as expected.
Just when I was showing off how easy is it to install a MySQL sandbox from a tarball, I was faced by an unexpected error. The tar application was not among the recognized ones. As soon as I saw

Came across an error on the sql for the overview.php page. It wasn’t correctly displaying aggregate data on the charts. So here’s the fix for rev50 to rev51.

Because of some weird bug my RSS feeds were broken ever since I’ve upgraded to WP 2.5. Today they were fixed and I hope they’ll have some new posts there soon Stay tuned.

Few days ago I’ve started migration of some of my non-critical servers to Debian Etch (from Sarge). Just after first apt-get update && apt-get dist-upgrade, when apt has been upgraded, I noticed really strange (as for me) error: when I’ve tried to do “apt-get update” it worked fine, but there was annoying message like following:

# apt-get update
......

Reading package lists... Done
W: There are no public key available for the following key IDs:

W: You may want to run apt-get update to correct these problems

UPDATE: Thanks to Kurt Fitzner we know, that:

There is already a mechanism to do this automatically:

$ apt-key update

This will obtain the necesary keys and import them. No need to
