I took a look at the MySQL 4.1.20 Changelog and as far as I can tell this fixes a issue within MySQL. Therefore it looks like it doesn’t require changes in the calling (for instance WordPress) programs.

And I would expect more people to experience this issue if it was a WordPress related issue.

Try asking them which version they were running before the upgrade. Maybe it’s something else that was changed that’s causing this issue.

I just spent a couple of hours playing with plug-ins on my site, so I dedicated a blog post to the ones I use.

Try the WordPress 2.0.3 Tuneup plugin. It should fix your issue

Ask your hosting service if they changed something to MySQL recently, because this sounds like an error on the database side if everything used to work.

You gave us just 6 minutes…

Miracles I do immediately, the rest takes some time.

You said you disabled it in the Options screen. Did you also disable it within your user profile page?

He wants a link to your blog, so we can see the problem ourselves. ??

Yes, you can do it with an iframe or something similar, but it’s not an optimal solution if you take useability/accesibillity/… into account.

Is the .shtml generated by something? Else it shouldn’t be too hard to convert it to .php.

You added those links to your post while adding entries to your blog. Therefore there’s no relation/link between your WordPress configuration and those links. And WordPress can’t change what it doesn’t know about.

Whenever I encounter stuff like this, I usually start by checking (and if needed, fixing) the XHTML validity. Most issues can be solved this way.

If you have shell access, try logging in to MySQL through the shell with the username and password from your wp-config.php file.

If that works, it’s most likely not a database connection problem..

I assume you’re talking about the wp head plugin, based on the error message?

But I’m afraid I can’t really help you, except asking if you tried re-uploading/re-installing the plugin?

Security updates aren’t released for nothing.

By not upgrading you leave yourself wide open for possible hack attempts.

If the choice is upgrading or waiting for somebody else to delete my blog (or worse), I know what I’d choose.

And the upgrade process isn’t that hard. Just follow the detailed upgrade instructions and you should be alright. (I did)

The suggestion with the upgrade page you provided sounds nice, but a lot of hosting services don’t allow file editing from the web, making this option ‘useless’ for a lot of people.
The current procedure doesn’t have such a dependency.

What version of WordPress are you running?

If it’s 2.0.3, try the WordPress 2.0.3 Tuneup plugin.

In the sidebar.php of your theme look for a call to the wp_list_cats function and give a hide_empty=0 argument to it.

So it should be looking something like this:
wp_list_cats(‘sort_column=name&hide_empty=0’);
