I use Adsense widget for WordPress Sidebar from Mike Smullin in this technology blog. It’s a simple widgetized plugin and I really like its simplicity. I was never bugged by this plugin until today when I found strange behavior when using this plugin for WordPress > 2.3.1. If I updated other widget positions and then tried to click configuration values for this plugin, I got empty form. Initially, I thought the configuration values were not saved properly and somehow missing (although later I found out that the data was still saved in the database, it was just not displayed). Hence, I decided to do further investigation and spend some time to provide bug fixes.
