I have received several feedback that the Automatic Plugin Upgrade feature in WordPress is causing problem with my plugins.
I want to say that ALL my plugins currently will not work with the Automatic Plugin Upgrade feature because there is a problem with the path. It is a little difficult for me to explain it here.
The new version of my plugins that I am going to release on 1st June 2008 will address this issue. In another words, if are using 1.30 or 2.30 beta of my plugins, the problem has been solved.
So in the mean time, DO NOT use the Automatic Plugin Upgrade feature for my plugin.
