This plugin is just a huge bug. Among the hundreds of plugins I've tried so far, all kinds, I had never seen anything this bad. Nothing works good: installation, configuration, adding/editing data, widgetizing, embedding. I just wonder why it's said on description that it works on WP 2.84, because definitly it does not. I tried it on a couple of test blogs, some without any other plugin installed, and this screws up the same way.
