In my previous post on WP 2.8 I mentioned the RSS Fatal error problem. I have found the cause of the problem and it is a plugin I use for the Lifestream page I have. The plugin in question is SimpleLife – the version I am using is 1.3 which seem to be the latest. The one on the WordPress.org site shows version 1.2 and the maintainers site gives a 404 error.
I have disabled the plugin and now the RSS feed on the Admin Dashboard is working fine with no Fatal Error. This has broken my Lifestream page. Will go and find a similar plugin to populate the Lifestream page.
