I've just released a new revision of the CaRP/WP WordPress plugin that integrates my RSS to HTML converter with WordPress. The new version adds support for the YouTube plugin that I just released for CaRP. Using it, you can display dynamically updating YouTube videos in your WordPress posts and pages.
The videos can be selected either by tags or by the YouTube user who uploaded the video.
I also added a workaround for a PHP bug that sometimes caused the output of a bunch of warning messages.
If you're using an older version of CaRP/WP, be sure to upload carp-wp-youtube-theme.php to your CaRP theme's directory.
The YouTube features requires CaRP Evolution 4.0 or higher.
