Hey Viper, I seem to be having issues with this plugin after upgrading to WP2.3, as well. It worked fine before the upgrade, but now the videos do not show up. You can view my posts with videos here: https://www.seodisco.com/category/video-clips/
I have tried disabling all plugins except for this one, but nothing changed. Any ideas? I thought I’d ask the creator before diving into it, myself. Thanks!
