WordPress 3.0 and 3.0.1 Upgrade Bug

Submitted by Igor on August 23, 2010 – 4:01 pmNo Comment

Ignoring my own advice to never install latest WordPress releases as soon as they come out, I upgraded my installation to WP 3.0 and shortly after to 3.0.1. Doing so broke a few things. Automatic plugin updates or installs seem to hang and so does automatic WordPress upgrade. Let me illustrate. According to this screenshot, I need to update one of the plugins.

No problem, I click on the plugin checkbox and then click “Update Plugins”. The following screen informs me that the maintenance mode has been enabled and the plugin update is underway.

This screen never refreshes. It will continue sitting at the “Updating Plugin…” prompt until the end of time. Surprisingly, the plugin actually updates quickly, but it is not reactivated. You have to go and activate it manually.

The same issue occurs when trying to reinstall WordPress by using the “Re-install Automatically” button. The screen gets stuck on the “Downloading update” prompt. Just like with plugin updates, the reinstall works. It’s just the page that never refreshes.

Things I’ve tried to fix this (unsuccessfully):

Remove the “.maintenance” file from the site’s root directory.
Re-create ./wp-content/upgrade directory with 755 or 777 permissions
Change permissions of wp-content to 777
Clean Firefox cache and cookies
Use IE
Use a browser on another computer
Reinstall WP manually
Restart MySQL and Apache
Reboot the server
Increase PHP memory allocation via php.ini, wp-config.php, and .htaccess
Adding “AddType x-mapp-php5 .php” to the .htaccess

Nothing worked. The WordPress dev team seem to be aware of the issue. There is an open ticket on their bug-tracking site. For now my only advice is to stay at version 2.9. If you already updated to 3.0 or later and having this problem, add your comment to the aforementioned ticket or open a new one. This is not a critical issue, just an annoying one. Hopefully, a fix will be developed soon.

OpenSUSE 11.4 Installation Overview

After enjoying taking apart Microsoft’s “cloud” Office 365 for the numerous shortcomings of its installation process, having to do the same for my favorite Linux distro – openSUSE – is rather upsetting. OpenSUSE installation routine went from nearly-flawless in 11.1 to mildly annoying in 11.3, arriving to moderately obnoxious in 11.4. What happened? Same as with Microsoft, poor installation workflow is to blame. One can always feel when desktop support people take over workflow tasks from server admins.

Simple Host Monitoring with SSH

Sometimes you just need something very simple to monitor a server or an application on a temporary basis. A basic ping monitor is fine, but it will only tell you if a server is responding on the network. It will not tell you if there is some other problem on the system. The script below relies on passwordless SSH setup to periodically log into the monitored nodes and check on their health by executing a local or remote script.

Windows Network Troubleshooting Script

I try my best to stay away from Windows. I wish my clients did the same. The usual difficulty of troubleshooting elusive network performance problems is amplified many-fold when there is a Windows computer at the end of the line. With Unix it’s relatively simple: run tests “a”, “b”, “c”, etc and follow the familiar process of elimination. With Windows in the picture the number of steps uses up all of the English alphabet and spills over well into the Russian one. And when you finally reach step “я”, you have to pull out your Chinese dictionary.
